摘要： A piezoelectric resonator having a small spurious resonance, a large frequency difference .DELTA.F between the resonant frequency and the anti-resonant frequency, adjustable capacitance, and high design flexibility includes a base member formed by laminating, for example, a plurality of piezoelectric layers and internal electrodes. When the length, width, and thickness of the base member are indicated by L, W and T, respectively, the dimensions of the member are selected to satisfy the conditions of L.gtoreq.2W and L.gtoreq.2T. 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.

摘要： A piezoelectric resonator which vibrates in a longitudinal vibration mode includes first insulating films disposed on a side surface of a base member so as to cover at least part of exposed portions of a first group of the internal electrodes and second insulating films disposed on the side surface of the base member so as to cover at least part of the exposed portions of a second group of the internal electrodes. A first thin-film external electrode extends continuously in the longitudinal direction of the base member on the first insulating films and a second thin-film external electrode extends continuously in the longitudinal direction of the base member on the second insulating film. A first conductive resin film and a second conductive resin film are respectively provided on the first thin-film external electrode and the second thin-film external electrode such that even if the thin-film external electrodes are broken or damaged, the piezoelectric resonator still functions.

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.

摘要： A piezoelectric component includes a substrate on which pattern electrodes are disposed. A piezoelectric resonator is placed on the substrate. The piezoelectric resonator generates a longitudinal vibration and includes a base member. External electrodes are disposed at both sides of a groove formed on one side surface of the base member. At the center of the base member in the longitudinal direction, support members made from an electrically conductive material are provided on the external electrodes. The support members are bonded to the pattern electrodes of the substrate via electrically conductive adhesive. An insulating adhesive is disposed between the support members. As a result of this structure, the piezoelectric component has a sufficient bonding strength between the base member and the piezoelectric resonator and prevents a short circuit from occurring between the support members formed in the piezoelectric resonator.
