Abstract: A driver includes a piezoelectric sheet, a fixing frame, a moving frame, and a control circuit. The piezoelectric sheet includes a first piezoelectric body portion which bends in a first direction, a second piezoelectric body portion which bends in a second direction that intersects at right angles with the first direction, and a connection portion which connects the first and second piezoelectric body portions. The fixing frame is fixed to the connection portion. The moving frame is supported on the first and second piezoelectric body portions. The control circuit applies voltage signals to the first and second piezoelectric body portions to bend the first and second piezoelectric body portions and which moves the moving frame in one of the first direction and the second direction or in a composite direction of the first direction and the second direction.
