Claims

[Claims for Utility Model Registration] (1) In a dielectric filter in which a plurality of resonator units each having a through hole are coupled by capacitive coupling and inductive coupling, each resonator unit is prismatic and the resonator The unit is bonded and integrated with a material having a lower dielectric constant than the dielectric of the unit, has an inner conductor film in the through hole, an outer conductor on the surface where the through hole is not exposed, and 1. A dielectric filter comprising a conductor film short-circuiting an inner conductor and an outer conductor on one of the exposed surfaces of the dielectric filter. (2) In a dielectric filter in which multiple resonator units equipped with through holes are coupled by capacitive coupling and inductive coupling, each resonator unit is prismatic and has a dielectric constant lower than that of the dielectric of the resonator unit. The through hole is bonded and integrated with a material having a low conductivity, and has an inner conductor film in the through hole, an outer conductor on the surface where the through hole is not exposed, and an inner conductor film on one of the exposed surfaces of the through hole. 1. A dielectric filter comprising a conductor film that short-circuits a conductor and an outer conductor, the inner conductor of a resonator unit at both ends being capacitively coupled to an input/output terminal.
