Abstract:
1. A method of manufacturing a stacked piezoelectric element, the method comprising: a layer stacking step of stacking a plurality of discrete cylindrical piezoelectric layers having different diameters inserted coaxially relative to each other and forming a cylindrical-shaped piezoelectric element, and an electrode layer on a circumferential surface of each of the cylindrical piezoelectric layers, by alternately and cylindrically applying a piezoelectric material paste including piezoelectric material powder and an organic vehicle as main components of the piezoelectric material paste and a conductive paste including conductive body powder and an organic vehicle as main components of the conductive paste; and a firing step of firing the piezoelectric layers and electrode layers stacked in the layer stacking step, wherein the conductive paste is dividedly applied to a plurality of discrete areas along the circumferential surface of the respective cylindrical piezoelectric layer, and wherein the electrode layer is divided among a plurality of discrete areas along the circumferential surface of the respective cylindrical piezoelectric layer.
