摘要： A rotary electric machine (1000) including: a rotor (200); a stator (100) surrounding a periphery of the rotor (200); a first recessed portion (133) disposed in an inner circumferential surface of a back yoke (130) of the stator (100), and extending in an axial direction of the stator (100); and a tooth (120) having one end fitted in the first recessed portion (133), a clearance formed between the first recessed portion (133) and the one end of the tooth (120) fitted in the first recessed portion (133) being smaller in a circumferential direction of the stator (100) than in a radial direction of the stator (100).
