    • Provided is an ultrasonic motor capable of realizing high torque. When two terminals are selected from a first terminal (31t), a second terminal (32t), and a third terminal (33t) of a vibrator (3), and AC voltages whose phases are shifted by 90 degrees relative to each other are respectively applied through both of those two terminals, vibration is generated in the stator vibration body (S), and elliptical vibration in a plane corresponding to the selected two terminals is generated at each of a step (9) of a first stator (2) and a corner (11) of a second stator (10), which are in contact with a rotor (6). Since the first stator (2) and the second stator (10) form the single stator vibration body (S), the step (9) of the first stator (2) and the corner (11) of the second stator (10) vibrate in the same vibration mode, rotational force is transmitted from both the step (9) of the first stator (2) and the corner (11) of the second stator (10), and the rotor (6) rotates with high torque.
