Abstract:
A manufacturing method of a piezoelectric/electrostrictive device comprising a driving portion including thin plates facing each other and a thin film piezoelectric/electrostrictive element formed on a surface of at least one of the thin plates, and a fixed portion and a movable portion each having a rectangular parallelpiped shape, wherein the thin plates facing each other are spanned so that sides of the movable portion and the fixed portion are continuous, said manufacturing method comprises the steps of:providing at least one green sheet to be one of the thin plates, at least one green sheet in which at least one hole portion having a rectangular shape is formed, and at least one green sheet to be the other one of the thin plates; laminating said green sheets to form an integrated layered body; forming a piezoelectric/electrostrictive element on a surface of the green sheets that form the thin plates by one of a thick film method and a thin film method; and cutting said layered body in the laminating direction of the green sheets so that said hole portion having a rectangular shape is open on the side of said layered body after sintering said layered body.
