an outer conductor casing, a plurality of resonant elements disposed within the outer conductor casing, and mounted opposite to each other on a side wall of the outer conductor casing, each center conductor being set opposite to the resonant element. Threaded rods are arranged protruding from the inner wall surface of the outer conductor housing near the center conductors of the input and output fittings, respectively, and the threaded rods are arranged on the concentric conductors. A band-pass filter characterized in that the open ends are capacitively coupled, and a notch filter for high frequency removal is formed depending on the coupling capacitance and the length of the threaded rod .
