1. 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 steps of;

    producing a ceramic laminate by firing a ceramic green laminate containing first ceramic green sheets and second ceramic green sheets for constituting said thin plate sections integrally, said first ceramic green sheets each having a window for forming at least said hole and one or more beam section;

    forming said piezoelectric/electrostrictive elements on a part of an outer surface of said ceramic laminate for constituting said thin plate sections; and

    producing a piezoelectric/electrostrictive device having at least one beam section from said inner wall of said movable section to said inner wall of said fixing section by cutting at least once said ceramic laminate having said piezoelectric/electrostrictive element.
