摘要： An inverter-integrated rotating electric machine includes an enclosure in which a vent hole is formed, an AC motor accommodated in the enclosure, the AC motor including a rotor and a fan whose rotation introduces external air into the enclosure from outside through the vent hole, the fan being fixed to the rotor, and an inverter unit accommodated in the enclosure and disposed in the vent hole. The inverter unit includes a power circuit portion and a control circuit portion whose control board is housed in a case which thermally isolates the control board from the power circuit portion. The power circuit portion is located at a position facing the fan and the control circuit portion is located upstream of the power circuit portion with respect to an inflow of the external air. Signal lines from the power circuit portion are connected to signal lines from the control circuit portion through holes formed in the case.
