    • A vibration actuator includes an elastic body on which at least one projection is formed and a vibrating body including an electromechanical conversion device, and drives a driven member that is in contact with a contact portion of the projection by causing an end portion of the projection to perform an ellipsoidal movement in response to a combination of two vibration modes generated in the vibrating body when an alternating driving voltage is applied. The elastic body is formed integrally with the projection and a bonding portion between the projection and the electromechanical conversion device. A space is provided between the contact portion and the electromechanical conversion device to which the projection is bonded. The spring portion is provided between the bonding portion and the contact portion and causes the projection to exhibit a spring characteristic when the contact portion is pressed by the driven member.
