ABSTRACT:
A mathod of manufacturing a piezoelectric/electrostrictive divice includes an additional member that is provided at a border between an inner wall surface of a thin plate section formed by a long ceramic plate and a side surface (cutout surface) formed by a short ceramic plate. Assuming that a surface of the additional member forms a curve C as viewed in vertical cross section, the curve C is a free curve having one inflection point. The additional member has a portion C2which extends along the inner wall surface of the thin plate section with its surface extending substantially in parallel toward the border, and a curved portion C3which is disposed at a part corresponding to the border.
