Abstract

A rotor for a rotating electric machine includes: a rotor core (12) having magnet holes; magnets (16) inserted in the magnet holes of the rotor core (12). Each of the magnets (16) includes two first surfaces (17a, 17b) respectively facing outward and inward of the rotor radial direction, and two second surfaces (18a, 18b) respectively facing one side and the other side of the rotor circumferential direction. Both ends in the rotor axial direction of at least one first surface of the two first surfaces (17a, 17b) are covered with electric insulating films, and a lateral surface region between both ends of the one first surface that are covered with the electric insulating films, and the two second surfaces (18a, 18b) are covered with no electric insulating films.
