A dynamo-electric machine in one embodiment of the present invention includes a tubular stator, a rotor disposed in an internal space of the stator, a bottomed tubular case that accommodates the stator, an end cover mounted on an open end of the case on one side, and a temperature sensor. The stator includes a stator core having a plurality of protruding portions that protrude toward a center of the stator, insulators mounted on the stator core, and a coil obtained by winding a winding wire around each of the plurality of protruding portions with the insulators therebetween. The temperature sensor is disposed on the end cover side of the stator between bent portions of the winding wires in the adjacent coils.
