Abstract
A dielectric filter including a plurality of coaxial type dielectric resonators having outer conductors and inner conductors is arranged so that the outer conductors are connected to each other. Also included in the dielectric filter are central conductors arranged to be brought into contact with the inner conductors of said plurality of coaxial type dielectric resonators and a dielectric substrate having thereon a plurality of substrate conductors whose number at least corresponds to the number of the plurality of coaxial type dielectric resonators, and input/output terminals provided on said dielectric substrate. The central conductors are respectively coupled to the substrate conductors provided on the dielectric substrate and inductance elements are connected to the substrate conductors which are positioned at both sides.
