A stepping motor includes a pair of drive coils arranged to sandwich a magnetic rotor in the axial direction of a rotor shaft in order to decrease the motor size. The drive coils are configured to be annular around the rotor shaft that extends in both directions from the magnetic rotor. A pair of cylindrical yokes are provided to enclose the drive coils. A pair of sintered bearings that support the rotational movement of the rotor shaft are made of a magnetic material, and the cylindrical yokes and the sintered bearings are formed together.
