Abstract

See full text

In a surface acoustic wave device, a plurality of surface acoustic wave elements include piezoelectric bodies having the same cut-angle. A propagation azimuth of a surface acoustic wave in at least one of surface acoustic wave elements is different from a propagation azimuth of a surface acoustic wave in at least another one of the surface acoustic wave elements. In each of the surface acoustic wave elements, a confinement layer configured to confine the surface acoustic wave inside the piezoelectric body is disposed on the piezoelectric body at the side opposite to the side where an electrode is located.
