Abstract

A metal member includes a plate-shaped portion provided on an upper main surface of a 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. A first electronic component is mounted on the upper main surface of the substrate and is disposed in front of the metal member. A second electronic component is mounted on the upper main surface of the substrate and is disposed behind the metal member. A sealing resin layer is provided on the upper main surface of the substrate and covers the metal member and the one or more electronic components. The plate-shaped portion is provided with one or more lower notches extending upward from the lower side. The metal member further includes a plurality of foot portions. All of the plurality of foot portions extend backward from the lower side.

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 metal member, the first electronic component, and the second electronic component, wherein
when viewed in the front-back direction, a line connecting a lower end of the plate-shaped portion in a left-right direction is defined as a lower side,
the plate-shaped portion is provided with one or more lower notches extending upward from the lower side,
the metal member further includes a plurality of foot portions, and
all of the plurality of foot portions extend forward from the lower side, or all of the plurality of foot portions extend backward from the lower side.

2. The module according to claim 1 , wherein
outer edges of the plurality of foot portions is connected to outer edges of the one or more lower notches when viewed in the front-back direction.

3. The module according to claim 2 , wherein
the one or more lower notches include a plurality of lower notches, and
the plurality of foot portions include a first foot portion located between the plurality of lower notches in the left-right direction when viewed in the front-back direction.

4. The module according to claim 1 , wherein
the plurality of foot portions include a second foot portion disposed at a left end portion or a right end portion of the lower side when viewed in the front-back direction.

5. The module according to claim 1 , wherein
the plurality of foot portions are arranged at equal intervals in the left-right direction when viewed in the front-back direction.

6. The module according to claim 1 , wherein
the one or more lower notches include a plurality of lower notches, and
the plurality of lower notches are arranged at equal intervals in the left-right direction when viewed in the front-back direction.

7. The module according to claim 1 , wherein
the one or more lower notches include a first lower notch disposed at a left end portion or a right end portion of the lower side when viewed in the front-back direction.

8. The module according to claim 1 , wherein
the one or more lower notches include two lower notches, and
the plurality of foot portions are not disposed between the two lower notches in the left-right direction when viewed in the front-back direction.

9. The module according to claim 1 , wherein
the plurality of foot portions are two foot portions,
the two foot portions are disposed at a left end portion and a right end portion of the lower side when viewed in the front-back direction,
the one or more lower notches include one lower notch, and
the one lower notch is disposed between the two foot portions in the left-right direction when viewed in the front-back direction.

10. The module according to claim 1 , wherein
a left end of the plate-shaped portion is located on a left surface of the sealing resin layer,
a right end of the plate-shaped portion is located on a right surface of the sealing resin layer, and
an upper end of the plate-shaped portion is located on an upper surface of the sealing resin layer.

11. The module according to claim 1 , further comprising:
a shield electrically connected to the metal member and covering an upper surface of the sealing resin layer.

12. 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 metal member, the first electronic component, and the second electronic component, wherein
when viewed in the front-back direction, a line connecting a lower end of the plate-shaped portion in a left-right direction is defined as a lower side,
the plate-shaped portion is provided with one or more lower notches extending upward from the lower side,
the metal member further includes a plurality of foot portions provided under the lower side, and
the plurality of foot portions include structure (A) foot portions or structure (B) foot portions:
(A)
each of the structure (A) foot portions includes a first portion extending downward and forward from the lower side of the plate-shaped portion and a second portion extending backward from a lower end of the first portion, and
a back end of the second portion is located below the back main surface of the plate-shaped portion or behind the plate-shaped portion;
(B)
each of the structure (B) foot portions includes a first portion extending downward and backward from the lower side of the plate-shaped portion and a second portion extending forward from the lower end of the first portion, and
a front end of the second portion is located below the front main surface of the plate-shaped portion or in front of the plate-shaped portion.

13. The module according to claim 12 , wherein
