description A rotary electric machine includes a cylindrical stator having a stator core on which stator coils are provided, and a rotor that is provided to be freely rotated in a hollow part of the stator and includes a rotor core supported on a rotating shaft and having a plurality of permanent magnets provided therein in a circumferential direction thereof, and a pair of end face plates provided at end parts in an axial direction of the rotor core, respectively. The rotor core has a refrigerant flow passage provided therein, the refrigerant flow passage passing through the rotor core in the axial direction. One end face plate of the pair of end face plates is provided with a refrigerant introducing section configured to introduce a refrigerant supplied via a refrigerant supply pipe into the refrigerant flow passage.
