ABSTRACT:
A surface acoustic wave device has a supporting substrates, a propagation substrate A made of a piezoelectric single crystal, an organic adhesive layer having a thickness of 0.1 to 1.0 μm and bonding the supporting substrate and the propagation substrate, and a surface acoustic wave filter or resonator provided on the propagation substrate. The temperature coefficient of frequency of the surface acoustic wave device can be thereby reduced.
