A stepping motor includes a stator, a rotor rotatably supported by the stator, and an auxiliary magnetic member. The auxiliary magnetic member has a body, side edge parts at both circumferential ends of the body, and an opening between the side edge parts. The auxiliary magnetic member is elastically mounted around a flange of the stator. The auxiliary magnetic member includes, at one of the side edge parts, a projecting part protruding radially inward from a projected inner circumferential surface of the body across the opening.
