SURFACE ACOUSTIC WAVE ELEMENT, ELECTRIC SIGNAL PROCESSING DEVICE USING THE SURFACE ACOUSTIC WAVE ELEMENT, ENVIRONMENT EVALUATION DEVICE USING THE ELECTRIC SIGNAL PROCESSING DEVICE, AND ANALYZING METHOD USING THE SURFACE ACOUSTIC WAVE ELEMENT
A surface acoustic wave element includes a base member (110, 210, 10) which has an annular surface (111, 211, 10b) formed by at least one portion of a spherical surface and continuing annularly, and which is made of a single crystal, and surface acoustic wave exciting means which excites a surface acoustic wave propagating along the annular surface.
