Abstract

In a module, a metal member includes a right support portion, the right support portion has a right support foremost portion located at a foremost in the right support portion and located in front of the plate-shaped portion, the right support portion bends in a forward direction from a right boundary when the right support portion has the right support foremost portion, the right support portion bends in a backward direction and a right direction from the right support foremost portion when the right support portion has the right support foremost portion, and the right support portion is provided with a first lower notch extending in an upward direction from a lower side and overlapping the right support foremost portion when viewed in the up-down direction.

First claim

1 . A module comprising:
a substrate having an upper main surface and a lower main surface arranged in an up-down direction; a metal member including a plate-shaped portion provided on the upper main surface of the substrate, the plate-shaped portion having a front main surface and a back main surface arranged in a front-back direction when viewed in the up-down direction; a first electronic component mounted on the upper main surface of the substrate and disposed in front of the metal member; a second electronic component mounted on the upper main surface of the substrate and disposed behind the metal member; and a sealing resin layer provided on the upper main surface of the substrate and covering the first electronic component, the second electronic component, and the metal member, wherein the metal member includes a right support portion, a boundary between the plate-shaped portion and the right support portion is defined as a right boundary, the right boundary is located at a right part of the metal member, the right support portion includes a right support foremost portion located at a foremost of the right support portion and located in front of the plate-shaped portion, or a right support rearmost portion located at a rearmost of the right support portion and located behind the plate-shaped portion, when the right support portion includes the right support foremost portion, the right support portion bends in a forward direction from the right boundary, when the right support portion includes the right support foremost portion, the right support portion bends in a backward direction and a right direction from the right support foremost portion, when the right support portion includes the right support rearmost portion, the right support portion bends in a backward direction from the right boundary, when the right support portion includes the right support rearmost portion, the right support portion bends in a forward direction and a right direction from the right support rearmost portion, when viewed in the up-down direction, a line connecting a lower end of the right support portion in a left-right direction is defined as a right lower side, and the right support portion is provided with a first right lower notch extending in an upward direction from the right lower side, the first right lower notch overlapping the right support foremost portion or the right support rearmost portion when viewed in the up-down direction.

2 . The module according to claim 1 , wherein
a first straight line parallel to a left-right direction is defined, and the first straight line overlaps at least two places of the right support portion.

3 . The module according to claim 1 , wherein the right support portion includes a right support front portion located in front of the plate-shaped portion in the front-back direction and a right support rear portion located behind the plate-shaped portion in the front-back direction.

4 . The module according to claim 1 , wherein
when the right support portion includes the right support foremost portion, the right support portion includes a first portion located between the right boundary and the right support foremost portion in the right support portion, and a second portion located between the right support foremost portion and a right end of the right support portion in the right support portion, when the right support portion includes the right support rearmost portion, the right support portion includes a first portion located between the right boundary and the right support rearmost portion in the right support portion and a second portion located between the right support rearmost portion and a right end of the right support portion in the right support portion, a straight line extending in the left-right direction is defined as a first straight line, the first portion is parallel to a second straight line when viewed in the up-down direction, the second portion is parallel to a third straight line when viewed in the up-down direction, and an angle at a corner formed by the second straight line and the third straight line is larger than an angle at a corner formed by the first straight line and the second straight line.

5 . The module according to claim 1 , wherein
when the right support portion includes the right support foremost portion, the right support portion includes a first portion located between the right boundary and the right support foremost portion in the right support portion, and a second portion located between the right support foremost portion and a right end of the right support portion in the right support portion, when the right support portion includes the right support rearmost portion, the right support portion includes a first portion located between the right boundary and the right support rearmost portion in the right support portion and a second portion located between the right support rearmost portion and a right end of the right support portion in the right support portion, the first portion draws a first arc around a first point when viewed in the up-down direction, the second portion draws a second arc around a second point when viewed in the up-down direction, and a curvature radius of the second arc is smaller than a curvature radius of the first arc.

6 . The module according to claim 1 , wherein the metal member is provided with a second lower notch in the right support portion, the second lower notch extending in the upward direction from the right lower side and overlapping the right boundary when viewed in the up-down direction.

7 . The module according to claim 1 , wherein
when viewed in the front-back direction, a line connecting upper ends of the plate-shaped portion in the left-right direction is defined as an upper side, and the plate-shaped portion is provided with an upper notch extending in a downward direction from the upper side.

8 . The module according to claim 1 , wherein
the substrate includes a mounting electrode and a conductive member, the mounting electrode and the conductive member being parts of the upper main surface of the substrate, the conductive member includes a right conductive member in contact with the right support portion, and the mounting electrode includes a right mounting electrode fixed to the right support portion by the right conductive member.

9 . The module according to claim 8 , wherein
when the right support portion includes the right support foremost portion, an area of a portion where the right conductive member is in contact with a back main surface of the right support portion is larger than an area of a portion where the right conductive member is in contact with a front main surface of the right support portion, and when the right support portion includes the right support rearmost portion, an area of a portion where the right conductive member is in contact with the front main surface of the right support portion is larger than an area of a portion where the right conductive member is in contact with the back main surface of the right support portion.

10 . The module according to claim 8 , wherein
when the right support portion includes the right support foremost portion, an area of a portion where the right conductive member is in contact with a front main surface of the right support portion is larger than an area of a portion where the right conductive member is in contact with the back main surface of the right support portion, and when the right support portion includes the right support rearmost portion, an area of a portion where the right conductive member is in contact with the back main surface of the right support portion is larger than a
