Claims

[Claims for Utility Model Registration] At least one dielectric resonator, which has one or more resonance through holes formed in a dielectric block, and a conductor layer formed on the inner and outer peripheral surfaces of the block. In a dielectric filter in which input/output and interstage coupling are performed on a coupling substrate, the substrate has protrusions on both opposing end surfaces, and the protrusion on one end surface is connected to the open end of the resonator. 1. A dielectric filter, which is inserted into a through hole and connected to a conductor layer on an inner peripheral surface, and has a protrusion on the other end surface serving as an input/output terminal.
