Abstract
While suppressing that a vibration of a piezo-electric element propagates to a substrate by devising the composition of an electro-conductive support body, the piezoelectric resonant component which secures electroconductivity and can maintain a fall-proof shock property is provided. The piezoelectric resonant component has a substrate on the top surface of which pattern electrodes and are formed, and on the lower surface of which it has electrodes and It has a piezoelectric element using the length vibration on the substrate Electro-conductive support bodies and are fixed to the length direction center section of the lower surface electrodes of the piezoelectric element The connection fixation of these support bodies and to the pattern electrodes and of the substrate is performed by electro-conductive adhesives and The electro-conductive support bodies and include an urethane resin which contains an electro-conductive filler, making the rate of content of the electro-conductive filler 75-85 wt %.
