PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of realizing a minimum number of parts, effective improvement in the rotational balance of a rotor, and high productivity and performance at low cost. SOLUTION: This rotary electric machine comprises a cylindrical stator core 10; the rotor 4 disposed on the inner periphery side of the stator core 10 and having a shaft 18; a yoke portion 19 formed integrally with the shaft 18; a magnet 20 fixed on the outer periphery of the yoke portion 19; a staged portion 18a integrally formed with the shaft 18 for positioning the magnet 20 by bringing one end of the magnet 20 in the axial direction into contact with it; and a protective cover 23 press fitted into the shaft 18 and protecting a corner 22 of the magnet 20.
