Provided is a high-torque low-noise rotary electric machine. In a rotary electric machine, a jumper conductor having a normal slot pitch connects slot conductors by striding slots with a slot pitch “Np=N(=6)” in one of coil ends and striding slots with a slot pitch “Np=N(=6)” in the other coil end, assuming that the number of slots per pole is set to “N(=6).” The jumper conductor having an irregular slot pitch connects the slot conductors by striding slots with a slot pitch “Np=N+1(=7)” in one of the coil ends and striding slots with a slot pitch “Np=N−1(=5)” in the other coil end, assuming that the number of slots per pole is set to “N(=6).” The stator winding has a plurality of slot conductor groups consisting of a plurality of slot conductors having the same phase.
