Abstract
A vibration driven device includes a vibration member having a plurality of projective portions, and an electro-mechanical energy conversion element contacting the vibration member. The conversion element has a plurality of electrodes, and the vibration member is vibrated by applying a signal to the electrodes. Each end portion of the plurality of electrodes of the conversion element is located coincident with one of the plurality of projection portions of the vibration member.
