Abstract:
A power module in which a heat generating component connected electrically to a wiring substrate is connected to a heat sink through the medium of a thermally conductive and electrically insulating member,wherein the thermally conductive and electrically insulating member is a curable composition containing (A) a thermosetting resin, (B) a thermoplastic resin, (C) a latent curing agent, and (D) an inorganic filler; the thermally conductive and electrically insulating member is bonded to the heat generating component in a complementary state to unevenness in shape and height of the heat generating component, and heat generated from the heat generating component is radiated by means of the heat sink; the heat generating component is mounted on one main surface of the wiring substrate, and at least one non-heat generating component is mounted on a surface opposite the one main surface; and at least one of the non-heat generating components is disposed in a position other than a position immediately opposite to the position of the heat generating component.
