Abstract
A SAW element includes a piezoelectric substrate, a support substrate attached to a bottom surface of the piezoelectric substrate, and an IDT electrode on a top surface of the piezoelectric substrate. A resonance frequency and an anti-resonance frequency of a resonator including the IDT electrode are kept between a frequency of a lowest frequency bulk wave spurious and a frequency of a next lowest frequency bulk wave spurious.
