The rotor of this electric motor comprises a rotor magnet 15. The rotor magnet 15 comprises a yoke 1 and a resin magnet section 16 that is arranged on the exterior of the yoke 1 and that is formed from a resin containing a rare-earth magnetic powder. A plurality of seats 5 and a plurality of connecting sections 6 are formed on the end surface 3a of the yoke 1. The connecting sections 6 connect adjacent seats 5. The connecting sections 6 are arranged in the center of the end surface 3a in the radial direction. The heights of the connecting sections 6 are lower than the heights of the seats 5. The present invention provides the effect of making it possible to reduce the amount of rare-earth magnetic powder used in a rotor magnet.
