PROBLEM TO BE SOLVED: To provide a piezoelectric resonant component capable of suppressing transition of vibration of the piezoelectric element to a substrate by contriving composition of a conductive support, keeping conductivity, and maintaining drop shock resistance. SOLUTION: Pattern electrodes 21 and 22 are formed on upper face of a substrate 20, a piezoelectric element 1 having electrodes 8 and 9 on its lower side and using lengthwise vibration is arranged on the substrate 20, conductive supports 10 and 11 are fixed on center of lengthwise direction of the lower electrodes of the piezoelectric element 1, and the supports 10 and 11 are fixed to the pattern electrodes 21 and 22 of the substrate 20 by electro conductive adhesive 12 and 13. The conductive supports 10 and 11 consist of urethane resin containing conductive filler with its content made from 75 to 85 wt.%.
