Abstract
A pair of opposing thin plate sections, movable sections, and fixed sections for supporting the thin plate sections and the movable sections are provided on a ceramic substrate. After a wiring pattern and a gap or an insulating layer of cermet layer for filling the gap are formed on a ceramic substrate, these are sintered. After that, piezoelectric/electrostrictive layers and cermet electrode layers including a piezoelectric/electrostrictive material and a conductive material are alternately stacked in a comb like structure on the ceramic substrate. Accordingly, a piezoelectric/electrostrictive device having the piezoelectric/electrostrictive element in multilayer structure is obtained.
