。In a rotor for a rotating electric machine having a structure in which a rotor shaft is provided in the axial direction at the cylindrical shaft center of a cylindrical magnet whose outer peripheral part is magnetized, the magnet is a hollow cylindrical magnet and one end surface is open. Place a metal cup-shaped cylindrical body, the other end of which is the bottom surface, on the inner diameter side of the hollow cylindrical magnet, so that the bottom surface of the cup-shaped cylindrical body is approximately at the center of the hollow cylindrical magnet in the axial direction. The cup-shaped cylindrical body has a plurality of small through holes in its bottom surface, and the bottom surface of the cup-shaped cylindrical body and the rotor shaft are integrally fixed by resin molding. In addition, this molded resin body is in close contact with the inner diameter surface of the hollow-cylindrical magnet and the cup-shaped cylinder near the bottom surface, but at both ends of the hollow cylindrical magnet, the outer diameter of the molded resin body is hollow. A rotor for a rotating electric machine, characterized in that the rotor is formed smaller than the inner diameter of a cylindrical magnet and a cup-shaped cylindrical body.
