摘要： On a substrate are configured piezoelectric elements composed of a mirror device, piezoelectric thin films, electrodes, and elastic members, and application of a voltage to the electrodes causes flexure deformation in the piezoelectric thin films, so that the mirror device is actuated. A plurality of the piezoelectric elements are arranged in parallel with a longitudinal direction thereof, and torsion springs are provided so as to extend in a direction orthogonal to the longitudinal direction and so as to hold the mirror device in connection with the substrate. The mirror device is connected to the piezoelectric elements through strain absorbers. In such a configuration, the torsion springs serve as a rotation axis, and the mirror device is inclined about the rotation axis.

摘要： 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.
