Abstract:
A method of producing a piezoelectric/electrostrictive device having a pair of mutually opposing thin plate sections, a movable section, and a fixing section for supporting said thin plate sections and said movable section, said piezoelectric/electrostrictive device comprising:one or more piezoelectric/electrostrictive elements arranged on at least one thin plate section of said pair of thin plate sections; and a hole formed by both inner walls of said pair of thin plate sections, an inner wall of said movable section, and an inner wall of said fixing section, comprising the step of: producing said piezoelectric/electrostrictive device and forming a mechanism for restricting amplitude of said thin plate sections by cutting off a predetermined portion of said thin plate sections after forming said piezoelectric/electrostrictive elements on at least the thin plate sections.
