Abstract:
A piezoelectric resonant component comprising:a substrate having a pattern electrode on a top surface thereof; a piezoelectric element vibrating in a longitudinal vibration mode and having an electrode that is disposed on a lower surface of the substrate; and an electro-conductive support body disposed at a longitudinal center of said piezoelectric resonant component and an the lower surface electrode of said piezoelectric element; wherein the electro-conductive support body includes an electro-conductive adhesive and is fixed to the pattern electrode of the substrate by the electro-conductive adhesive, the electro-conductive support body includes a urethane resin containing an electro-conductive filler that is about 75% to about 85% by weight of the electro-conductive support body; said electro-conductive support body has a Young's modulus of less than about 1.00Ã—109 Pa; and the electro-conductive support body is provided and arranged to eliminate vibrations of the piezoelectric element from propagating to the substrate.
