A rotating electric machine , and an electric wheel using the rotating electric machine, has a rotatably supported rotor and a stator separated by a prescribed gap from the rotor, wherein the rotor has a magnetic pole ring formed from a circular permanent magnet, and a core piece embedded in the permanent magnet. The magnetic pole ring has outer and inner peripheral surfaces formed in a ring shape, wherein one of the outer peripheral surface and the inner peripheral surface is a gap-facing surface that faces the aforementioned gap, and the other is a non-gap-facing surface different from the gap-facing surface. The non-gap-facing surface of the magnetic pole ring is configured from the permanent magnet, the gap-facing surface of the magnetic pole ring is configured containing the permanent magnet and the exposed core piece, and the permanent magnet is magnetized such that the core piece is the magnetic center.
