PROBLEM TO BE SOLVED: To suppress an increase of a dimension in the axial direction of a rotating electric machine by simplifying the wiring structure of stator coils. SOLUTION: The rotating electric machine incudes: a rotor 1 connected to a load; a stator core 10, which is a cylinder that covers the rotor 1 and on the inside circumferential surface of which a plurality of grooves 14 extending in the axial direction are formed side by side with intervals in the circumferential direction; and stator coils 20 wound on the grooves 14. The stator coils 20, which have a plurality of sets of three-phase coils with three phases forming one set, are wound in such a way that the coil ends 23 of each three-phase coil is extended from each end at the load side and the anti-load side of the stator core 10 toward the outside in the axial direction. A plurality of circuit rings 31, which are arranged outside in the axial direction of each end at the load side and the anti-load side of stator core 10 with predetermined intervals, are electrically connected to the coil ends 23.
