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 20 on the top surface of which pattern electrodes 21 and 22 are formed, and on the lower surface of which it has electrodes 8 and 9. It has a piezoelectric element 1 using the length vibration on the substrate 20. Electro-conductive support bodies 10 and 11 are fixed to the length direction center section of the lower surface electrodes of the piezoelectric element 1. The connection fixation of these support bodies 10 and 11 to the pattern electrodes 21 and 22 of the substrate 20 is performed by electro-conductive adhesives 12 and 13. The electro-conductive support bodies 10 and 11 include an urethane resin which contains an electro-conductive filler, making the rate of content of the electro-conductive filler 75-85 wt %.

Description

technical field [0001] The present invention relates to piezoelectric resonant elements such as an oscillator, a phase detector, and a filter, and more particularly to a piezoelectric resonant element in which a piezoelectric element vibrating in a longitudinal vibration mode is mounted on a substrate element. Background technique [0002] Conventionally, an electrically conductive support is fixed to the center portion (node ​​portion) of the lower surface electrode of the piezoelectric element, which vibrates in the longitudinal vibration mode. When the support body is connected to the patterned electrode on the substrate via a conductive adhesive, the upper surface electrode of the piezoelectric element is connected to the patterned electrode of the other substrate via wire bonding. A piezoelectric resonance element having such a structure has been disclosed, for example, in Japanese Unexamined Published Patent Application JP10-200366. The electroconductive support is f...
