ABSTRACT:
A driving device for a motor has a mounting substrate mounted to a base substrate. Highly heat-generating components such as a switching element for PWM control are mounted to the mounting substrate and only less heat-generating circuit components are mounted to the base substrate. The mounting substrate has a base plate part made of a metallic plate material surround by a molded insulating material but includes a heat dissipating part where the insulating material is removed and the internal metallic plate material is exposed.
