ABSTRACT:
A vibration wave driven motor having an electromechanical energy conversion member for generating a vibration wave in an elastic member. This conversion member has first and second surfaces opposite to each other, and first and second surfaces respectively formed on the first and second electrodes to receive an applied electrical signal. The first electrode is formed in a position such as to face one side of the elastic member and has an electrical signal input terminal provided on the second surface side of the conversion member. This input terminal and the first electrode are electrically connected by, for example, a conductor formed in a through hole. It is thereby possible to supply an electric current to each electrode with reliability while maintaining the conversion member and the elastic member in desired close contact with each other.
