Abstract
A method of producing a surface acoustic wave device includes a sacrificial-layer forming step of forming a sacrificial layer on a piezoelectric substrate so as to cover comb electrodes and reflectors, a space-forming-member forming step of forming a space-forming member while openings are formed near the reflectors along a surface of the sacrificial layer, a sacrificial-layer removing step of removing the sacrificial layer from the openings of the space-forming member, and a resin sealing step of sealing a surface acoustic wave element with sealing resin, the surface acoustic wave element having an excitation protection space formed between the reflectors and the comb electrodes by the space-forming member.
