A vibration driven motor including a plurality of polarized piezo-electric elements disposed on a vibrator, in which cyclic signals different in phase selectively are applied to the respective elements to form standing waves to drive a moved body. A direction of polarization of each of the piezo-electric elements in the motor is identical. A plurality of consecutive elements are grouped, and cyclic signals of predetermined phase selectively are applied to predetermined element groups.
