ことを特徴とする誘電体フイルタ。[Claims for Utility Model Registration] A filter element using a dielectric coaxial resonator, a case for housing the filter element, an input/output terminal provided on the filter element, and a dielectric constituting the filter element. In a dielectric filter equipped with a plurality of ground terminals that are electrically connected to the outer conductor of a coaxial resonator, the input/output terminals are arranged so as to face a transmission line formed on a mounting surface of a board on which the dielectric filter is mounted. The arm terminals are formed so as to be substantially parallel to the mounting surface of the board in the mounted state, and at least some of the plurality of arm terminals are formed in the mounted state so that they can be inserted and fixed into through holes provided in the board. A dielectric filter, characterized in that it is formed substantially perpendicular to the mounting surface of the substrate.
