The rotating electric motor includes a stator including a stator coil (2b) and a stator core, and a rotor (3) located at an inner peripheral side of the stator core and rotatable relative to the stator. The rotor (3) includes a rotor core (6) provided at an outer periphery of a rotor rotation shaft via a core support portion. The rotor core (6) has a plurality of magnetic poles in which a plurality of sets of permanent magnets (8) are provided along a circumferential direction. The rotor core (6) includes a plurality of rotor core divided bodies (6a), (6a) that are aligned in an axial direction, concentrically arranged, and shifted in phase from each other by a determined angle (¸s). A pair of grooves (10), (10) are provided on an outer peripheral portion of each rotor core divided body (6a) to be spaced apart from each other in the circumferential direction with a center (L1) or (L2)of each magnetic pole.
