Abstract
The dimension in a moving direction of a vibration wave motor is shortened without impairing the thrust force, and the size of a driver is reduced. The vibration wave motor includes a vibrating plate having a substantially rectangular outline, a piezoelectric element bonded to the vibrating plate and configured to vibrate, and a protrusion provided to the vibrating plate or the piezoelectric element. The vibrating plate has a section not covered with the piezoelectric element inside a rectangular region encompassing the piezoelectric element within a plane where the piezoelectric element is bonded, and also has a notched portion along a straight line which passes through the section and is parallel to one side of the outline of the vibrating plate.
