Claims

[Scope of utility model registration request]

On the upper surface of an insulating substrate made of ceramic, an energy-enclosed two-terminal piezoelectric resonator and a capacitive element formed of two sets of capacitor parts on a single high-permittivity electromagnetic plate are fixed by adhesive bonding on one side of the two. Furthermore, on the upper surface of the insulating substrate, there are a recess for protecting the excitation electrode on the adhesive side of the piezoelectric resonator, a plurality of conductive paths for connecting the piezoelectric resonator and the capacitive element to a desired piezoelectric oscillation circuit, and a plurality of conductive paths for connecting the piezoelectric resonator and the capacitor to a desired piezoelectric oscillation circuit. An insulating cover member is provided to cover the upper part of the elements and hermetically encapsulate them, and further, the ends of the conductive paths for wiring are exposed on the surface of the insulating substrate as terminals for connecting to an external circuit.
