A rotary electric machine (100) comprises a stator (20) and a rotor (40), wherein, in order to suppress vibrational noise of the stator (20) in which a plurality of divided cores (10) that are arranged along the circumferential direction of an annular frame(30) are press-fitted into the annular frame, each of the divided cores (10) is constituted of a first steel plate (11) and a second steal plate (11) fixed together by a crimped section (12), and wherein the crimped section (12) has a gap (13) in a radial direction of the stator (20) such that the first steel plate (11) and the second steel plate (11) are able to move relative to each other in the radial direction and the area of a contact surface where the lamination surface of the steel plates (11) of the divided core (10) touch against the frame (30) is made large.
