Piezoelectric/electrostrictive device having mutually opposing end surfaces and method of manufacturing the same

摘要

A piezoelectric/electrostrictive device comprises a pair of mutually opposing thin plate sections, a movable section, and a fixation section for supporting the thin plate sections and the movable section. A piezoelectric/electrostrictive element is arranged on at least one thin plate section of the pair of thin plate sections. A hole is formed by the inner walls of the pair of thin plate sections, the movable section and the fixation section. A central portion of the movable section is cut off to form mutually opposing end surfaces in the movable section.
