    • A dielectric resonator filter comprises dielectric resonators, an enclosure having a main body, a lid, and partition walls, interstage-coupling tuning windows, interstage-coupling tuning bolts, input/output terminals, and input/output coupling probes. Resonance-frequency tuning members each composed of a conductor plate and a bolt coupled integrally thereto are attached to the enclosure lid. Spurious-mode suppressing means such as rings (71,72) attached to the bolts of the resonance-frequency tuning members or bolts attached to the conductor plates or to the enclosure lid are disposed in an spurious-mode excitation space, whereby the occurrence of a disturbed characteristic in the pass band (or stop band) is suppressed. In another embodiment, the spurious-mode suppressing means comprise tuning plates (61y,61b) of different sizes.
