ABSTRACT:
A dielectric filter having a generally box-like dielectric block, an outer conductor covering side surfaces of the dielectric block, a plurality of inner conductors arranged in the dielectric block in the longitudinal direction so as to extend between two opposite faces of the block, and a short-circuit conductor provided in one of the two faces of the dielectric block to connect the outer and inner conductors. At least one of the inner conductors has a rectangular cross-sectional shape, and the size of this sectional shape in the longitudinal direction of the dielectric block is increased at the face where the short-circuit conductor is provided, and is reduced at the other face.
