To provide a vibrating element which can be driven by a low voltage, a vibration actuator, a lens barrel, a camera system and a method for driving a vibration actuator. A vibrating element (10) is provided with an elastically deformable tube-like member (11) having a hollow section (15); and an input sections (13 (13-1 to 13-4)), which are arranged on the outer surface of the tube-like member (11) and/or the inner surface of the tube-like member on the side of the hollow section (15), are divided into n (n is an integer of 3 or more) in the circumference direction of the tube-like member (11), and permit the tube-like member (11) to input a physical signal. |
