Abstract:
1. A producing method of a piezoelectric/electrostrictive film comprising the steps of: forming a piezoelectric/electrostrictive material layer on a solid-phase support; firing the piezoelectric/electrostrictive material layer to form a piezoelectric/electrostrictive film, which includes a first bonded region which is bonded in a predetermined pattern to the solid-phase support, and a second bonded region which is bonded to the surface of the solid-phase support, wherein a bonding strength between said piezoelectric/electrostrictive film and said solid-phase support in said second bonded region is greater than that in said first bonded region; and separating the first bonded region from the solid-phase support so that the second bonded region remains bonded to the solid-phase support.
