Vibration wave driving device and method of processing vibrating member or moving member for use in vibration wave driving device

摘要

In order to manufacture a vibration wave driving device in a short time and with high accuracy, the device of the invention comprises: a vibrating member which has an elastic member and an electro-mechanical energy conversion element and which causes vibration when a drive signal is applied to the electro-mechanical energy conversion element; and a moving member coming into contact with the vibrating member and driven by the vibration, characterized in that contact portions of the vibrating member and the moving member are formed such that at least one contact portion protrudes toward the other contact portion and that the vibrating member or the moving member having the protruding contact portion has in a same plane as an end surface of the protruding contact portion a surface of a part other than the protruding contact portion.
