Abstract

A spherical elastic surface wave element (100) includes: a spherical base (111); a pair of comb-shaped electrodes (112) which excite an elastic surface wave going around the surface of the base (111) and receives the elastic surface wave which has gone around the surface; a first and a second I/O electrode (114) which are formed in the vicinity of the two pole points of the optical axis passing through the center of the base (111) and connected to the respective comb-shaped electrodes (112); an external terminal (115) formed on the first I/O electrode (114); and an external electrode (116) formed to oppose to the second I/O electrode (114) in a non-contact way.
