Patent ID: 6883215

Claim:
A method for producing a piezoelectric/electrostrictive device comprising: a pair of mutually opposing thin plate sections, a movable section, and a fixation section for supporting said thin plate sections and said movable section; 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 fixation section, said method comprising the steps of: producing a ceramic substrate having said thin plate sections and said hole; forming said one or more piezoelectric/electrostrictive elements on at least one of said thin plate sections; and cutting off a predetermined portion after forming said piezoelectric/electrostrictive element on at least said thin plate section to produce said piezoelectric/electrostrictive device in which at least one thin plate section of said pair of thin plate sections is previously bent in a direction to make mutual approach.
