Abstract
A stacked piezoelectric element is produced by alternately stacking a piezoelectric layer and an inner electrode layer. The method includes producing a green sheetfor a base, forming a unit bodyhaving a narrow stacked partwhere a narrow piezoelectric material layerhaving an area smaller than the green sheetfor base and an electrode material layerhaving an area smaller than the green sheetfor base are stacked, the unit body being formed by disposing the narrow stacked parton the green sheetfor base; forming a stacked body having groove parts by stacking a plurality of the unit bodies, the groove part having the bottom being defined by the side face of the narrow stacked part; and firing the stacked body.
