ABSTRACT:
A microactuator includes: a stage on which a positioning object is to be mounted; a frame to which the stage is fixed integrally; a piezoelectric device disposed on the frame, which deforms in an expanding or contracting manner based on a driving signal applied; and a drive which applies a driving signal to the piezoelectric device. The piezoelectric device is arranged to expand or contract to thereby apply a torque to the frame.
