A technique of employing a rotor having anti-saliency and being rotatable about a predetermined axis in an axial gap type motor is provided. A plurality of magnets are disposed annularly on a substrate with polarities being symmetric around a shaft hole. For instance, the magnets exhibit N pole and S pole, respectively, on the side of a stator (on this side of sheet of drawing). A plurality of magnetic members are disposed to extend perpendicularly to the direction of a rotation axis, and more specifically, between the magnets.
