A rotor includes a rare-earth magnet magnetized in a radial direction, a rotor core, and a thermal conduction sheet formed of a deformable material. The rotor core includes a first part, a thin-wall part including a second part that is harder than the first part, and a magnet insertion hole. The thin-wall part is situated between a region of end of the magnet insertion hole in a circumferential direction and an outer edge of the rotor core.
