誘電体フイルタ。[Claims for Utility Model Registration] 1. A plurality of resonator holes and coupler holes are arranged alternately in the longitudinal direction of a rectangular parallelepiped dielectric block, and the resonator holes of the dielectric block are open. In a dielectric filter having an integral structure in which one of the surfaces is an open surface and the other end is a short-circuit surface, and a conductor film is formed on the outer surface other than the open surface and the inner surface of the resonator hole, a short circuit is formed inside the coupler hole. 1. A dielectric filter comprising a metallic substance that is electrically connected to the short-circuited surface from the surface side. 2. The dielectric filter according to claim 1, wherein the metallic substance is a conductive film attached to the inner wall of the connector hole.
