ABSTRACT:
A piezoelectric filter for use in electrical and electronic equipment which includes a substrate of piezoelectric material, and electrode members provided on first and second surfaces of the substrate so as to form at least one set of resonator including a multi-mode resonator and a single resonator of the thickness-vibration, energy-trapping type. The multi-mode resonator serves as a series resonance element of a ladder type filter through utilization of the oblique or anti-symmetrical mode resonance of the multi-mode resonator, while the single resonator is used as a parallel resonance element of the ladder type filter.
