Vibration wave driving apparatus and manufacturing method of vibration body

Abstract

A vibration wave driving apparatus according to the present invention includes a vibrator having at least a vibration body formed with a projecting portion having spring characteristics and an electro-mechanical energy conversion element, the vibration wave driving apparatus using motion of the projecting portion to drive a driven body in contact with the projecting portion, wherein the vibration body includes a base portion and the projecting portion, the projecting portion includes two wall portions formed in parallel to a direction orthogonal to a drive direction of the driven body extending in an out-of-plane direction with respect to the base portion and two wall portions formed in parallel to the drive direction of the driven body extending in an out-of-plane direction with respect to the base portion and a contact portion including a contact surface with the driven body formed by connecting the wall portions.
