A rotor includes a shaft, a rotor core, magnets on a radial outside surface of the rotor core, and sheet-shaped magnetic portions provided on radial outside surfaces of some of the magnets. The magnets include first magnets in which the magnetic portions are on a circumferential portion in a radial outside surface of the first magnets and second magnets in which the magnetic portions are not on a radial outside surface of the second magnets. The first magnets and the second magnets are alternately arranged in the circumferential direction in each of a first portion and a second portion along the axial direction in the radial outside surface of the rotor core. The first magnets of the first portion and the second magnets of the second portion overlap each other, and the second magnets of the first portion and the first magnets of the second portion overlap each other.
