Abstract

An electric component module includes a substrate including a first metal foil provided on a first surface, and a second metal foil provided on a second surface and in which a via hole that penetrates from the first surface to the second surface and electrically connects the first metal foil and the second metal foil is provided, a heat generating component disposed away from the substrate, a heat transfer resin that has contact with the substrate and the heat generating component, a metal member that is disposed on an opposite side of the heat generating component with the substrate therebetween and disposed away from the substrate, a heat dissipation member that has contact with the substrate and the metal member, and a heat transfer pin to be inserted into the via hole. A part of the heat transfer pin has contact with the heat transfer resin.

Claims (35)

1 . An electric component module comprising:

a substrate to include a first surface, a second surface facing an opposite side of the first surface, a first metal foil provided on the first surface, and a second metal foil provided on the second surface, in which a via hole that penetrates from the first surface to the second surface and electrically connects the first metal foil and the second metal foil is provided;

a heat generating component disposed away from the substrate in a plate thickness direction of the substrate;

a heat transfer resin to be disposed between the substrate and the heat generating component and have contact with the substrate and the heat generating component;

a metal member disposed on an opposite side of the heat generating component with the substrate therebetween and disposed away from the substrate in the plate thickness direction of the substrate;

a heat dissipation member to be disposed between the substrate and the metal member and have contact with the substrate and the metal member; and

a metal heat transfer pin to be inserted into the via hole, wherein

the first metal foil and the via hole are formed at positions overlapping at least the heat generating component as viewed along the plate thickness direction of the substrate, and
