Abstract
An actuator includes a frame, a driver portion having one end connected to an inside of the frame, a movable portion connected to another end of the driver portion, and an electrode provided at the movable portion. The driver portion vibrates the movable portion by being driven by a driving signal. The electrode receives a high-frequency signal higher than that of the driving signal. This actuator is driven at a high speed by a large deflection angle, and can prevent dust from adhering to the movable portion.
