Abstract
A method for producing a piezoelectric element by superposing a piezoelectric material made of a piezoelectric ceramic composition containing a PbMgNbO—PbZrO—PbTiOternary system solid solution composition represented by the general formula Pb(MgNb)TiZrOas a main component, and 0.05 to 10.0 mass % of NiO on a ceramic substrate or on an electrode formed on the ceramic substrate, and subjecting the superposed piezoelectric material to a thermal treatment in an atmosphere where 0.03–0.5 mg/cm(NiO conversion amount per unit volume of a space in a container) of an atmosphere-controlling material having the same composition as the piezoelectric material is coexisted.
