Abstract: An axial gap type motor according to the present invention includes: a rotor; and a pair of stators which are arranged to face each other and hold the rotor from both sides thereof along a rotation axis. The rotor includes: electromagnets which are provided on the rotor as main magnets, and arranged along a circumferential direction so that directions of magnetic fluxes thereof are parallel to the rotation axis; and sub permanent magnets which are provided on the rotor, arranged in the vicinities of circumferential end portions of the main magnets, and are magnetized orthogonal to the rotation axis and a radial direction.
