Description

ABSTRACT:
A piezoelectric/electrostrictive device is provided, including a pair of mutually opposing thin plate sections and a fixation section for supporting the thin plate sections. A piezoelectric/electrostrictive element is arranged on each of the thin plate sections. The piezoelectric/electrostrictive device also includes movable sections defined by at least first end portions of the thin plate sections and a material which is different from that of the thin plate section.
