Abstract:
A piezoelectric resonance component, comprising:a capacitor substrate; a piezoelectric resonance element mounted on the capacitor substrate; and a cover member fixedly attached to the capacitor substrate so as to enclose the piezoelectric resonance element, wherein the capacitor substrate includes a dielectric substrate, a plurality of inner electrodes arranged in layers within the dielectric substrate with a dielectric layer sandwiched therebetween, and a plurality of outer electrodes each electrically connected to at least one of the inner electrodes and disposed on at least one of a pair of side-edge surfaces of the dielectric substrate which are opposite to each other; and the plurality of inner electrodes include an inner electrode connected to a ground potential and a pair of split inner electrodes located at a common vertical position within the capacitor substrate and spaced apart from each other with respect to a central portion of the dielectric substrate, the pair of split inner electrodes and the inner electrode connected to a ground potential are arranged to face each other with the dielectric layer disposed therebetween.
