Abstract:
A composite substrate for an acoustic wave element includes a support substrate 1 and a propagation substrate 3 for propagating an acoustic wave. The propagation substrate is bonded to the support substrate 1 and composed of a piezoelectric single crystal. The propagation substrate 3 includes a surface lattice distortion layer 11 in which crystal lattices of the piezoelectric single crystal are distorted.
