A rotary electric machine of the present invention includes, inside a housing, a rotor and a stator that are concentric with each other. The stator has a plurality of coil portions in a circumferential direction. In the stator, a first flow channel and a second flow channel, through which cooling water flows, are provided along the plurality of coil portions, each of the channels having one end connected to a flow channel inlet and the other end connected to a flow channel outlet. The lengths of the first flow channel and the second flow channel are mutually different. A temperature detection element is provided in a coil portion on a high temperature side among the coil portions positioned along the first flow channel and the coil portions positioned along the second flow channel.
