A small and low-price rotating electric machine has a structure where a magnet end surface and a metal tube end are not in contact with each other. The rotating electric machine has a cylindrical stator core, a rotor having a shaft provided on the inner circumferential side of the stator core, a yoke fixed to the shaft, at least one ferrite magnet provided on the outer circumferential surface of the yoke, and a protective cover provided on the outer circumference of the ferrite magnet. The ferrite magnet end surface is projected with respect to an end surface of the yoke, and has a step portion to form a gap between the end surface of the ferrite magnet and a bottom surface of the protective cover.
