Abstract:
A piezoelectric oscillator comprising:a capacitor substrate having a first main surface and a second main surface, a pair of side surfaces, and a pair of end surfaces; first and second external electrodes including portions extending to the first main surface of the capacitor substrate; a third external electrode not extending to the first main surface; a piezoelectric resonator mounted on the first main surface and electrically connected to the first and second external electrodes; a parallel capacitance section connected between the first and second external electrodes to load a capacitance in parallel to the piezoelectric resonator; and a pair of load capacitance sections arranged to interpose a load capacitance between the first and third external electrodes and a load capacitance between the second and third external electrodes; wherein the parallel capacitance section and the pair of load capacitance sections are located inside of the capacitor substrate.
