An object is to release heat efficiently to heat-resistance abilities of individual components by enhancing a heat-radiation performance of power circuit components forming a power module (100) and by enhancing a heat generation balance. The power circuit components formed of power switching elements (107 and 108) forming a bridge circuit and a motor relay switching element (109) are mounted on conductive members (102) while a heat generation balance is maintained. Then, the conductive members (102) are disposed on a heat-releasing heat sink (30) by abutment, and the power circuit components and the heat sink (30) are integrally molded using mold resin (101).
