Abstract
In a rotating electric machine, a rotor core has a rotor core cooling hole under a state of being coupled to a first gap at a position on a radially inner side with respect to a center portion of a first inner wall surface in a length direction. The rotor core has a radially-outer-side refrigerant flow path formed under a state of being coupled to a radially-outer-side end portion of the first gap. A first end plate has a communication path formed so as to extend from an inner end surface of the first end plate to the rotor core cooling hole. A second end plate has a discharge path formed so as to allow the radially-outer-side refrigerant flow path to communicate with an outside.
