る導波管形バンドパスフイルター。 A plurality of reactance elements are arranged in a plurality of stages at predetermined intervals in the longitudinal direction of the main waveguide in a direction that crosses a wide surface of the main waveguide, and each resonance between the reactance elements adjacent in the longitudinal direction of the main waveguide is generated. An opening is provided in the narrow surface of the main waveguide in correspondence with the main waveguide, and one end of the sub-waveguide is connected to the narrow surface outside the main waveguide using the opening as a communication port. In a waveguide type bandpass filter in which a short plate is provided at the other end of the wave tube, a screw or bolt is screwed into the short plate so as to pass through the sub waveguide in the tube axis direction. A waveguide bandpass filter characterized by:
