Abstract

A method of producing a SAW (Surface Acoustic Wave) device, including the steps of implanting ions in an entire surface of a piezoelectric member of the SAW device, so that an ion implantation layer is formed therein; performing a heat treatment of the piezoelectric member, so that a heat-treated ion implantation layer is formed in the entire surface of the piezoelectric member; and providing an electrode of a comb type resonator on the heat-treated ion implantation layer.
