ABSTRACT:
A piezoelectric resonator comprises a piezoelectric substrate, a common electrode layer applied on one major surface of the piezoelectric substrate, and at least one electrode layer applied on its second major surface. The piezoelectric substrate is held in position between two or more metallic terminal elements, with the electrode layers held in electrical contact with the terminal elements. The piezoelectric resonator further comprises at least one direction-oriented electroconductive sheet positioned between the electrode layer on the second major surface of the piezoelectric substrate and the associated terminal element. The direction-oriented electroconductive plastic sheet has substantial electroconductivity only across its thickness.
