るフイルタ。[Claims for Utility Model Registration] A dielectric block, an inner conductor formed on the inner wall surface of a through hole penetrating from one end face of the dielectric block to another end face opposite thereto, and an inner conductor surrounding the through hole. It has a plurality of resonant units consisting of an outer conductor formed on the outer surface of the dielectric block, and a short-circuit conductor that short-circuits the inner conductor and the outer conductor by using the one end surface of the dielectric block as a short-circuit end, and In a filter comprising a dielectric coaxial resonator formed in the dielectric block between matching resonant units and having a coupling hole for coupling between the adjacent resonant units, the dielectric block has a A cap made of a metal material that shields the opening of the coupling hole is fitted onto the short-circuited end at a predetermined distance from the short-circuited end so as not to affect the filter characteristics, and is electrically connected to and fixed to the outer conductor. A filter characterized by:
