Abstract
An actuator of the present invention includes a shape maintaining sheet, a piezoelectric member provided integrally on the shape maintaining sheet, and a pair of electrodes formed to sandwich the piezoelectric member, wherein the shape maintaining sheet is formed of synthetic resin. Since the piezoelectric member is thin, the stiffness is increased by the shape maintaining sheet made of synthetic resin, and thus resonance frequency can be adjusted.
