PROBLEM TO BE SOLVED : To provide a rare earth magnet motor increased in rigidity of a stator core and a rotor yoke while reduced in size and lightened in weight of a motor. SOLUTION : In a rare earth magnet motor, a stator core 4 is integrally molded with a housing 2 without discontinuity by a dust core made by compression molding of magnetic powder having an insulation film formed on a surface thereof, and a rotor yoke 9 is integrally molded with an output axis 8 without discontinuity by a dust core made by compression molding of magnetic powder having an insulation film formed on a surface thereof. A recessed portion 20 in which a coil is accommodated is formed on an inner peripheral surface of the housing 2, on both end sides of the stator core 4 in the axial direction.
