PROBLEM TO BE SOLVED: To provide a rotary electric machine that can be reduced in noise.SOLUTION: In a rotary electric machine comprising a stator winding having a plurality of corrugated circumferential windings and a rotator supported rotatably on a stator core 232 via a clearance, when the number of slots in each pole is set as N (=6), a crossover conductor 233b connects the slot conductors to each other so as to stride over a slot at slot pitch Np=N+1 (=7) at one coil end and to stride over the slot at slot pitch Np=N-1 (=5) at the other coil end. The stator winding has a plurality of slot conductor groups constituted of a plurality of slot conductors 233a with the same phase, and the plurality of slot conductors 233a of the slot conductor groups 234 are inserted through a predetermined number Ns of slots arrayed consecutively in a circumferential direction of the stator core so that a slot 237 and layers L1-L4 are adjacent, where the predetermined number Ns of slots is set to Ns=NSPP+NL(=4) when the number of slots in each pole and each phase is set as NSPP(=2) and the number of layers is set as 2×NL(=4).
