Abstract:
1. A method of manufacturing a piezoelectric device comprising: providing material of composition consisting essentially of three components, Pb(Zn 1/3 Nb 2/3 )O 3 , PbTiO 3 , and PbZrO 3 , and having a basic composition formula of Pb(Zn 1/3 Nb 2/3 ) x Zr y Ti z O 3 , where 0.97≦x+y+z<1.0; firing the material; pulverizing the fired material so that the pulverized material has an average particle diameter ranging from 0.6 μm to 1.5 μm; making a ceramic sheet from the pulverized material; making a multilayer body by stacking the ceramic sheet and paste containing silver; and sintering the multilayer body at a temperature not higher than 900° C.
