Abstract
An acoustic wave resonator includes a piezoelectric substrate and an IDT electrode on the top surface of the piezoelectric substrate. Between a resonance frequency and anti-resonance frequency due to a surface acoustic wave, one to four of at least one of resonance frequencies or anti-resonance frequencies due to bulk waves are located.
