Patent ID: 7649306

Claim:
A piezoelectric component comprising: a piezoelectric oscillating element composed of a pair of electrodes disposed on both major surfaces of a piezoelectric substrate so as to at least partially face each other with the piezoelectric substrate therebetween; a pair of frames arranged on the respective major surfaces of the piezoelectric substrate so as to surround the regions of the pair of electrodes facing each other; a pair of sealing substrates composed of a light-transmissive resin material arranged so as to cover the respective external surfaces of the pair of frames; a pair of input/output terminal electrodes respectively connected to the pair of electrodes; and ground terminal electrodes on the side faces of the piezoelectric substrate, wherein the pair of electrodes consists of vibrating electrodes facing each other with the piezoelectric substrate therebetween, extractor electrodes connecting the vibrating electrodes to the input/output terminal electrodes, and capacitor electrodes protruding from the vibrating electrodes or the extractor electrodes toward the ground terminal electrodes and generating capacitors with the ground terminal electrodes.
