ABSTRACT:
A method of manufacturing a piezoelectric ceramic resonator, comprising the steps a of preparing a piezoelectric ceramic plate, polarizing the piezoelectric ceramic plate, and adjusting an anti-resonance frequency of the piezoelectric ceramic plate, by lapping the same to adjust its thickness while measuring the anti-resonance frequency thereof. Preferably a homogeneous material is used as the piezoelectric ceramic plate in this manufacturing method.
