ABSTRACT:
The present invention relates to a surface acoustic wave element comprising a substrate, an optical waveguide layer formed on the aforesaid substrate to guide laser light from a laser light source, a surface acoustic wave portion for deflecting or modulating the laser light traveling through the aforesaid optical waveguide layer, a comb-shaped SAW electrode provided on the aforesaid optical waveguide layer to cause the aforesaid surface acoustic wave portion to generate surface acoustic wave, and a terminal provided on the aforesaid optical waveguide layer and connected to the aforesaid SAW electrode to apply a high-frequency alternating voltage thereto, wherein a protection cover is bonded by a viscoelastic adhesive having a refractive index smaller than that of the aforesaid optical waveguide layer to cover the aforesaid SAW electrode and surface acoustic wave portion with air space in such a manner that the aforesaid terminal is positioned outside thereof, and the manufacturing method of the surface acoustic wave element.
