Abstract: In a rotating body (32) of a rotor (30), a plurality of permanent magnets (45) are arranged in a circumferential direction, alternating with a plurality of divided cores (33). The plurality of permanent magnets (45) is in surface contact with side surfaces of the divided cores (33) in the circumferential direction in a state where facing magnetic pole faces of two permanent magnets (45) arranged on both sides of each divided core (33) in the circumferential direction are homopolar. In a resin covering portion (50) of the rotating body (32), a first part (51) and a second part (52) cover end surfaces of the plurality of permanent magnets (45), a plurality of third parts (53) covers outer peripheral surfaces of the plurality of permanent magnets (45), and a fourth part (54) covers inner peripheral surfaces of the plurality of divided cores (33) and inner peripheral surfaces of the plurality of permanent magnets (45).
