Abstract
A rotating electric machine includes a rotor and a stator. The rotor includes: a rotor core having a refrigerant flow path; and an end surface plate arranged at least on one side of the rotor core. The refrigerant flow path includes: a first refrigerant flow path; and a second refrigerant flow path which is disposed further on a radial inner side than the first refrigerant flow pat. The stator includes: a stator core; and a coil end portion protruding from at least one side of the stator core. The end surface plate includes: a root side refrigerant supply portion which communicates with the first refrigerant flow path and supplies the refrigerant to a root region of the coil end portion; and a distal side refrigerant supply portion which communicates with the second refrigerant flow path and supplies the refrigerant to a distal region of the coil end portion.
