ABSTRACT:
A piezoelectric/electrostrictive device that includes a base11having a pair of right and left movable parts11a,11band a fixing part11cdisposed at one end thereof as well as piezoelectric/electrostrictive elements12a,12bdisposed on the sides of the movable parts11a,11bof the base11is fabricated to have a construction with fewer components. The piezoelectric/electrostrictive device having a construction with fewer components is provided by adopting a base11having an integral structure formed by bending an original plate stamped into a shape that delineates a plane development of the base, as the base of the piezoelectric/electrostrictive device. In addition, in this piezoelectric/electrostrictive device, piezoelectric/electrostrictive elements are arranged on inner sides of a pair of left and right movable parts. Accordingly, destruction of the piezoelectric/electrostrictive element can hardly occur and high reliability of the piezoelectric/electrostrictive device is achieved.
