Claims

[Claims for Utility Model Registration] An inner conductor is provided on the inner surface of a through hole in a dielectric, an outer conductor is provided on the outer surface of the dielectric except for the open surface where the through hole is formed, and input/output is provided to the inner conductor on the open surface. A dielectric filter in which a dielectric block formed by capacitively coupling terminals is housed in a housing-like metal case in which the input/output terminal holes are formed in the bottom surface and the housing-like metal case is electrically connected to the outer conductor and grounded. The other set consists of a bottom face, two side faces of one set extending from both sides of the bottom face and bent at right angles and facing each other, and four bent extensions extending from both sides of the two sides facing each other. The bottom surface or the two sides of the other set are connected so that the two sides of the other set are electrically connected to the bottom face.
1. A dielectric filter comprising a connecting conductive piece that extends from a side surface and is bent at right angles, and a dielectric block is housed in the metal case.
