PROBLEM TO BE SOLVED: To provide a polarized waveguide dielectric filter with a structure providing an optional attenuation pole leading to a simple structure with high productivity wherein reducing the discontinuity caused between input output terminals of the filter and signal lines of a board to the utmost in the case of mounting the filter onto the board decreases the loss caused by reflection or radiation of an electromagnetic field at an input/output section. SOLUTION: In the waveguide dielectric filter wherein a plurality of dielectric waveguides are integrally configured to a dielectric block, a plurality of the dielectric waveguides configuring the filter are formed to the dielectric block, a dielectric waveguide to form an attenuation pole is formed at least to one side of them, and an input output dielectric body is placed between them, and input output electrodes by conductor strips are provided to a bottom face of the input output dielectric body. One-side ends of the conductor strips are led to a side end face, and the branched other ends are extended to the bottom side of the dielectric waveguides configuring the filter and the bottom side of the dielectric waveguide forming the attenuation pole.
