A stepping motor includes: a stator including a coil that is wound so as to form a hollow space; a rotor including a magnet to be disposed in the hollow space of the coil, the rotor being rotationally driven by changing magnetic poles of the stator;and a magnetic member that is disposed adjacent to the coil so that a direction of a polarity of the magnet and a direction of a winding axis of the coil in a stable position of the magnet cross each other when the coil is excited or when not excited.
