ABSTRACT:
A piezoelectric/electrostrictive membrane element is provided, including a ceramic substrate, a membranous piezoelectric/electrostrictive portion including a piezoelectric/electrostrictive body made of a large number of crystal particles having a lead zirconate titanate based piezoelectric/electrostrictive ceramic composition, and membranous electrodes electrically connected to the piezoelectric/electrostrictive portion. The crystal particles include crystal main body portions, and surface layer portions arranged in at least a part of the outer periphery of crystal main body portions and having a crystal structure which is different from that of the crystal main body portions. The piezoelectric/electrostrictive portion is bonded in a solid state to the substrate directly or via electrodes.
