Abstract
A method for making a piezoelectric element including a piezoelectric film formed on a substrate by a gas deposition technique includes the steps of ejecting ultra-fine particles of a piezoelectric material having a perovskite structure from an ejecting device toward the substrate, and applying an electric field to the ultra-fine particles traveling to the substrate. The substrate may be composed of a metal or a resin.
