PIEZOELECTRIC DEVICE, ITS MANUFACTURING METHOD AND METHOD FOR MANUFACTURING PIEZOELECTRIC OSCILLATOR

摘要

PURPOSE: A piezoelectric device is provided to have a structure which resists impact from the outside and to improve electrical conductance between an electrode side of a package base and a piezoelectric resonator element. CONSTITUTION: A piezoelectric resonator element(11) is bonded to electrodes(44) on a package base(42). The device comprises underlying exposed electrodes(44) as mounting electrodes which are on the package base(42) and on which the piezoelectric resonator element(11) is mounted; and gold-plated electrodes(41) which are on the package base and to which a driving voltage is carried via conduction paths. The underlying exposed electrodes(44) and the gold-plated electrodes(41) are connected to each other with conductive adhesive(45) therebetween, and the piezoelectric resonator element is bonded to the underlying exposed electrodes with silicone-based conductive adhesive(15) therebetween.
