摘要： A piezoelectric/electrostrictive device 10 includes a stationary portion 11; a thin-plate portion 12 supported by the stationary portion; and a piezoelectric/electrostrictive element 14 including a plurality of electrodes and a plurality of piezoelectric/electrostrictive layers arranged alternatingly In layers. The piezoelectric/electrostrictive device 10 is manufactured by the steps of forming a piezoelectric/electrostrictive laminate by alternatingly laminating laminar electrodes and piezoelectric/electrostrictive layers on a plane of a thin-plate member adapted to form the thin-plate portion 12, and cutting the thin-plate member and the piezoelectric/electrostrictive laminate. The cutting step is performed by advancing a wire member (wire saw) reciprocating in a direction parallel to the direction of lamination of the piezoelectric/electrostrictive laminate while holding the wire member substantially parallel to the direction of lamination. Thus, since the laminar electrodes are cut while being extended within corresponding layer planes, the degree of covering the end surfaces of the piezoelectric/electrostrictive layers decreases.

摘要： A piezoelectric/electrostrictive device includes a pair of thin plates confronting each other, a fixing member supporting the thin plates thereon, and movable portions disposed on end portions of the pair of thin plates. Protrusions are formed on principal surfaces of first ceramic green sheets according to at least a single thick film forming process. The protrusions will subsequently serve as the movable portions, and the first ceramic green sheets will subsequently serve as the thin plates. The first ceramic green sheets and a second ceramic green sheet which will subsequently serve as the fixing member are stacked into a ceramic green laminated body. The ceramic green laminated body is baked into an integral ceramic laminated body. Piezoelectric/electrostrictive elements are formed on the ceramic laminated body. After the piezoelectric/electrostrictive elements are baked, unnecessary-portions are removed from the piezoelectric/electrostrictive elements to fabricate the piezoelectric/electrostrictive device.

The piezoelectric/electrostrictive device having a construction with fewer components is provided by adopting a base 11 having 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.
