Abstract
A piezoelectric/electrostrictive deviceincludes a stationary portion; a thin-plate portionsupported by the stationary portion; and a piezoelectric/electrostrictive elementincluding a plurality of electrodes and a plurality of piezoelectric/electrostrictive layers arranged alternatingly In layers. The piezoelectric/electrostrictive deviceis 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, 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.
