ABSTRACT:
A surface acoustic wave device wherein a laminated structure comprised of a piezoelectric member and a metal electrode or electrodes is provided on a surface acoustic wave surface of an elastic body and an acoustic impedance discontinuous face is formed on the elastic body, so that a longitudinal wave generated by the laminated structure is reflected by the acoustic impedance discontinuous face to provide a transverse wave.
