Abstract
A comb-line type dielectric filter in which a plurality of resonator holes are made in a dielectric block at predetermined intervals and coupling adjustment holes are made between the resonator holes, the interior surfaces of the resonator holes and the surface of the dielectric block being entirely or partly covered with a conductor film. The coupling adjustment holes are disposed apart from the line joining the centers of the resonator holes, and a coupling adjusting member made of metal or dielectric material is inserted into each coupling adjustment hole.
