Summary:In an ECU attached to a motor assembly, inverter FETs, which generate outputs for driving a motor, are electrically connected to a substrate. A plurality of screw holes is formed in a heat sink thereby to fix the substrate. A resin member is provided between the heat sink and the substrate and has a plurality of motor terminals and a resin mold, which integrally fix the motor terminals by molding the motor terminals. The motor terminal has an embedded part, a L-shaped substrate-side exposed part and a motor-side exposed side including a curbed part. The resin member and the substrate are tightened together and fixed to the heat sink.
