Abstract The present invention provides a piezoelectric resonance component, having the character that it includes a capacitor substrate, a piezoelectric resonator mounted on the capacitor substrate, and a cover member fixedly attached to the capacitor substrate. The capacitor substrate includes a dielectric substrate, a plurality of inner electrodes arranged in layers within the dielectric substrate, and a plurality of outer electrodes disposed on at least one of opposed side surfaces of the dielectric substrate. The plurality of inner electrodes include an inner electrode to be connected to a ground potential and a pair of split inner electrodes located at a common vertical position and spaced apart from each other with respect to a central portion of the dielectric substrate.
