Provided is a rotary electric machine that is able to suppress vibration noise of the rotary electric machine caused by an out-of-plane deformation. The rotary electric machine includes a stator including a frame being an annular member, and a plurality of split cores arranged in an annular shape and fitted to and held by a radially inner portion of the frame, wherein the frame is formed such that an inner diameter of each of both end portions thereof is smaller than an inner diameter of an axial middle portion thereof, and fitting fastening force between the frame and each split core is set to be greater at both the end portions than at the axial middle portion.
