摘要： A piezoelectric component achieves a desired Qm by using a presently available piezoelectric material. The piezoelectric component includes a supporting substrate on which pattern electrodes are provided. Electroconductive supporting members are disposed on the pattern electrodes, and a piezoelectric resonator is mounted on the supporting members. External electrodes of the piezoelectric resonator and the pattern electrodes are electrically connected to each other by the supporting members. Gaps between the piezoelectric resonator and the supporting substrate are filled with a first elastic material element. A second material element may be provided on the surface of the piezoelectric resonator disposed opposite to the surface of the resonator facing the supporting substrate. Only one of these elastic material elements or both these elastic material elements may be used.

摘要： A piezoelectric component has a substantially stronger connection between a substrate and a piezoelectric resonator and has improved electrical reliability. The piezoelectric resonator includes an insulating substrate having pattern electrodes disposed therein. A piezoelectric resonator capable of vibrating, for example in a longitudinal vibration mode is mounted on the substrate. A supporting member prepared separately as a pre-formed material member is bonded to the piezoelectric resonator at a nodal point of the resonator. A first flat surface of the supporting member is bonded to a vibrating electrode on the piezoelectric resonator by a first bonding and supporting material while a second flat surface of the supporting member is bonded to one of the pattern electrodes on the substrate by a second bonding and supporting material. The length of bonding between the piezoelectric resonator and the first bonding and supporting material along the longitudinal direction of the piezoelectric resonator is preferably set to about 25% or less of the overall length of the piezoelectric resonator. A central portion of another vibrating electrode of the piezoelectric resonator is connected to the other pattern electrode on the substrate by a conductor wire.

The base member is polarized at both ends of each internal electrode in opposite directions. A groove is preferably formed on one lateral surface of the base member, and at both sides of the groove, the internal electrodes are alternately covered with two insulating films. The two insulating films are respectively formed to cover the different internal electrodes. External electrodes are formed on both sides of the groove of the base member and are connected to the internal electrodes.
