Abstract
A process for producing PZT films on a substrate by thick-film technique in which the PZT films contain simply modified PZT and/or PZT with complex perovskite. PZT with a Zr content X of X.gtoreq.X.sub.p +0.02.ltoreq.X.sub.p +0.10 is used, where X.sub.p is the Zr content of the base composition at the morphotropic phase boundary determined by the maximum coupling factor K.sub.r.
