PROBLEM TO BE SOLVED: To provide a stepping motor capable of simplifying a rotational control method for a rotor portion, and a control circuit, and realizing size reduction and high-speed operation of the rotor portion. SOLUTION: This stepping motor 1 is capable of normal and reverse rotations which is constituted of the rotor portion 2 consisting of at least a permanent magnet, a stator portion 3, and a rotor portion rotational control means 4 which controls the rotation of the rotor portion 2. At least two statically stable positions P of the rotor portion 2 are provided in between the rotor portion 2 and the stator portion 3, and the rotor is structured so as to be rotated by 360 degrees with one-step operation pointer.
