摘要
A surface acoustic wave device which comprises: a plurality of interdigital transducers formed on a surface acoustic wave substrate; and a plurality of thin film electrodes disposed between the interdigital transducers and an end surface of the surface acoustic wave substrate and electrically independently of the interdigital transducers, at least one of distances between adjacent ones of the thin film electrodes being set to be smaller than a distance between the thin film electrodes and the interdigital transducers, so that the electrical performance of the device as well as the insulation resistance does not deteriorate, and the interdigital transducers can be prevented from being electrostatically broken.
