This rotating electric machine comprises: a stator having a stator core around which a plurality of coils are wound; a rotor supported to be rotatable relative to the stator with a predetermined gap therebetween; a rotor case that holds the rotor; and a first bearing and a second bearing that rotatably support the rotor case. The rotating electric machine includes: a first flow path formation body that forms a first flow path through which a refrigerant flows to a coil end part protruding from the stator core; a first case part which forms an accommodation space of the first bearing, is connected to the first flow path of the first flow path formation body, and fills the accommodation space with the refrigerant; a second flow path formation body which forms a second flow path through which the refrigerant flows to a coil end part disposed on the opposite side from the coil end part in the axial direction; and a second case part which forms an accommodation space of the second bearing, is connected to the second flow path of the second flow path formation body, and fills the accommodation space with the refrigerant.
