摘要： To provide a rotary electric machine can suppress from enlarging the outer diameter of the rotary electric machine due to mounting of the power module and the heatsink. A rotary electric machine (100) is provided with a power module (160) that is provided with a power semiconductor device (166H, 166L) which turns on and off energization to the windings (32); a heatsink (110) that is thermally connected to a heat sink fixing face (16) of the power module (160); and a refrigerant passage (160) through which a refrigerant flows in an arrangement space of the heatsink (110), wherein the heatsink fixing face (16) of the power module (160) extends in the radial direction (Y) and in the axial direction (Z), and wherein in the refrigerant passage (180), the refrigerant flows in the radial direction (Y) in the arrangement space of the heatsink (110).
