    摘要： In a dielectric resonator, through holes (2a-2d) are formed between opposing two surfaces (S1, S2) of a dielectric block (1), an outer conductor (6) is provided on an outer peripheral surface of the dielectric block, and a plurality of inner conductors (3a-3d, 4a-4d) are formed on the inner surfaces of the through holes, isolated by non-conducting portions (5a-5d) where the inner conductor is not provided. Near the open end of the inner conductor of the resonator hole, a non-conducting portion (8b, 9a) is formed by partially removing the inner conductor in the axial direction, at a position opposing to an adjacent through hole, or a position near the outer conductor, so as to increase odd mode or even mode characteristic impedance near the open end, and inductive coupling is enhanced.
