ABSTRACT:
A piezoelectric resonator comprising a piezoelectric substrate having a tapered portion as viewed from the side thereof, and drive electrodes provided on both opposing tapered surfaces of said tapered portion. The piezoelectric resonator corrects the dispersion in the thickness of the piezoelectric substrate relying upon the positions where the drive electrodes are formed, and makes it easy to finely adjust he frequency for compensating the dispersion in the thickness.
