摘要： In a controller-integrated electric rotating machine provided with a power circuit unit and a control circuit unit, a cooling property is improved so that the control circuit unit does not impair a flow of air for cooling the power circuit unit. A power circuit unit having switching elements for converting DC power to AC power for supplying the AC power to an electric rotating machine, a control circuit unit for controlling the switching elements of the power circuit unit, and a rotational position detection sensor arranged on a rotating shaft for detecting the rotation of the rotating shaft are provided. The control circuit unit is disposed, when viewed in the direction of the rotating shaft, at a position where the power circuit unit is not disposed and is shifted radially outward so as not to overlap the rotational position detection sensor.
