Abstract
A piezoelectric/electrostrictive device that includes a basehaving a pair of right and left movable partsand a fixing partdisposed at one end thereof as well as piezoelectric/electrostrictive elementsdisposed on the sides of the movable partsof the baseis fabricated to have a construction with fewer components. The piezoelectric/electrostrictive device having a construction with fewer components is provided by adopting a basehaving 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.
