Abstract
A capacitor-included, chip-type piezoelectric resonator allows minute and highly precise adjustment of electrostatic capacitance and the resonance frequency after production of the piezoelectric resonator by laminating a piezoelectric element and dielectric substrates. The resonator includes a piezoelectric substrate laminated with dielectric substrates and external electrodes disposed on the laminate body. A plurality of external electrodes are arranged to extend from the outer major surface of the first dielectric substrate to the outer major surface of the second dielectric substrate along first and second side surfaces disposed opposite to each other. On the outer major surface of the second dielectric substrate, at least one external electrode is divided into first and second electrode portions.
