ABSTRACT:
A piezoelectric resonator including a base, two conducting posts which pass through the base and a piezoelectric plate. The plate includes a central active zone which is surrounded by a peripheral zone. The two zones are connected by at least two bridges which define slits which separate the central zone from the peripheral zone. Each face of the central zone is covered with an adherent electrode which extends over one of the bridges to a part of the peripheral zone. Each of the electrodes is connected to one of the conducting posts through a conductive metal ribbon. Each of the metal ribbons bear on the inner part of the peripheral zone so that the ribbon is disposed substantially as an extension of the corresponding posts.
