摘要： A rotary electric machine according to the present invention includes: a stator including an outer core, a plurality of inner cores, and a coil accommodated in slots, each slot being surrounded by opposing circumferential side surfaces of tooth portions of adjacent inner cores and by inner circumferential surfaces of projections of the adjacent inner cores; and a rotor. A gap is provided between the circumferential side surfaces of the adjacent inner cores. The coil has a first slot-accommodated portion and a second slot-accommodated portion accommodated in different slots, and a turn portion connecting the two slot-accommodated portions on one end surface, in an axial direction, of a stator core. The turn portion is elastically urged in a direction in which the first slot-accommodated portion and the second slot-accommodated portion move away from each other in the circumferential direction.
