Patent ID: 7089637

Claim:
A method of producing a piezoelectric/electrostrictive device having a base including a pair of movable parts opposing each other, a fixing part that connects the movable parts with each other at one end thereof, and mounting parts that extend for a predetermined length while holding slit-shaped gaps of a predetermined width along inside surfaces of said movable parts by being turned around at the other end of said movable parts, said piezoelectric/electrostrictive device having a piezoelectric/electrostrictive element disposed on at least one outside surface of said movable parts of said base, wherein a flexible and bendable flat plate made of metal is adopted as a material for forming said base, and the base including said movable parts, said fixing part, and said mounting parts is formed by stamping said flat plate into a shape that delineates a planar development of said base so as to obtain a stamped structure, and bending said stamped structure at a predetermined site.
