description A rotor that is downsized while achieving high output of the electric motor is provided. The rotor includes a plurality of main magnets and a plurality of auxiliary magnets. The auxiliary magnets are fit into a plurality of respective grooves formed along a rotation shaft direction in an outer periphery of a rotation shaft arranged at the center of the rotor, are projected from the outer periphery of the rotation shaft to an outer side of a radial direction, and have a magnetization direction along a circumferential direction of the rotor. Magnetic field directions of the auxiliary magnets that are adjacent to each other are opposite to each other in the circumferential direction. The main magnets are arranged in projected parts of the auxiliary magnets that are adjacent to each other and have a magnetization direction that is along the radial direction of the rotor.
