Abstract

A module includes a substrate and a first metal member. The substrate has an upper main surface and a lower main surface arranged in an up-down direction. The first metal member includes a first plate-shaped portion provided on the upper main surface of the substrate, and includes a front main surface and a back main surface arranged in a front-back direction when viewed in an up-down direction. The first metal member further includes a first left support portion. A boundary between the first plate-shaped portion and the first left support portion is defined as a first left boundary. The first left support portion bends with respect to the first plate-shaped portion at the first left boundary so as to be located behind the first plate-shaped portion.

First claim

a first metal member including a first plate-shaped portion provided on the upper main surface of the substrate, the first 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 first metal member;
a second electronic component mounted on the upper main surface of the substrate and disposed behind the first metal member; and
a sealing resin layer provided on the upper main surface of the substrate and covering the first metal member, the first electronic component, and the second electronic component,
wherein
the first metal member further includes a first left support portion,
a boundary between the first plate-shaped portion and the first left support portion is defined as a first left boundary,
the first left boundary is located on a left part of the first metal member,
the first left support portion bends with respect to the first plate-shaped portion at the first left boundary so as to be located in front of or behind the first plate-shaped portion,
a lower end of the first plate-shaped portion and a lower end of the first left support portion are fixed to the substrate, and
a first left lower notch extending in an upward direction from the lower end of the first plate-shaped portion and the lower end of the first left support portion is provided such that a lower end of the first left boundary is located above the lower end of the first plate-shaped portion and the lower end of the first left support portion.

2. The module according to claim 1 , wherein the first left support portion extends in a forward direction or a backward direction from the first plate-shaped portion at the first left boundary.

3. The module according to claim 1 , wherein
when viewed in the front-back direction, a line connecting the lower end of the first plate-shaped portion in a left-right direction is defined as a first plate-shaped portion lower side,
the first plate-shaped portion is provided with one or more first plate-shaped portion lower notches extending in an upward direction from the first plate-shaped portion lower side, and
a position of an upper end of the first left lower notch in the up-down direction is a same as a position of an upper end of each of the first plate-shaped portion lower notches in the up-down direction.

4. The module according to claim 1 , wherein
when viewed in the front-back direction, a line connecting the lower end of the first plate-shaped portion in a left-right direction is defined as a first plate-shaped portion lower side,
the first plate-shaped portion is provided with one or more first plate-shaped portion lower notches extending in an upward direction from the first plate-shaped portion lower side, and
an upper end of the first left lower notch is located below an upper end of each of the first plate-shaped portion lower notches.

5. The module according to claim 1 , wherein
the first left support portion extends in a forward direction or a backward direction from a left end of the first plate-shaped portion,
when viewed in a left-right direction, a side connecting the lower end of the first left support portion in the front-back direction is defined as a first left support portion lower side, and
the first left support portion is provided with one or more first left support portion lower notches extending in an upward direction from the first left support portion lower side.

6. The module according to claim 1 , further comprising a second metal member including a second plate-shaped portion provided on the upper main surface of the substrate, the second plate-shaped portion including a front main surface and a back main surface arranged in the front-back direction when viewed in the up-down direction,
wherein
the first left support portion extends in a backward direction from the first plate-shaped portion at the first left boundary,
the second metal member further includes a second right support portion,
a boundary between the second plate-shaped portion and the second right support portion is defined as a second right boundary,
the second right boundary is located at a right part of the second metal member,
the second right support portion bends with respect to the second plate-shaped portion at the second right boundary so as to extend in a forward direction from the second plate-shaped portion at the second right boundary,
a lower end of the second plate-shaped portion and a lower end of the second right support portion are fixed to the substrate, and
a distance between a back end portion of the first left support portion and a front end portion of the second right support portion is shorter than a length of the first left support portion in the front-back direction.

7. The module according to claim 1 , further comprising a second metal member including a second plate-shaped portion provided on the upper main surface of the substrate, the second plate-shaped portion including a front main surface and a back main surface arranged in the front-back direction when viewed in the up-down direction,
wherein
the first left support portion extends in a backward direction from the first plate-shaped portion at the first left boundary,
the second metal member further includes a second left support portion,
a boundary between the second plate-shaped portion and the second left support portion is defined as a second left boundary,
the second left boundary is located on a left part of the second metal member,
the second left support portion bends with respect to the second plate-shaped portion at the second left boundary so as to extend in a forward direction or a backward direction from the second plate-shaped portion at the second left boundary,
a lower end of the second plate-shaped portion and a lower end of the second left support portion are fixed to the substrate, and
a distance between a back end portion of the first left support portion and a right end portion of the second plate-shaped portion is shorter than a length of the first left support portion in the front-back direction.

8. The module according to claim 1 , wherein
the first metal member further includes a first right support portion,
a boundary between the first plate-shaped portion and the first right support portion is defined as a first right boundary,
the first right boundary is located at a right part of the first metal member,
