Abstract
An actuator is provided which can be driven with a simple configuration and by simple control. The actuator comprises a thin film made of a shear piezoelectric material, a first electrode formed on a first main surface of the thin film, and a second electrode formed on a second main surface of the thin film. A driving force is generated on at least one end edge of the thin film by applying a predetermined AC voltage between the first electrode and the second electrode.
