A dielectric filter capable of easily obtaining desired filter characteristics by strongly coupling mutually adjacent resonators with high accuracy even when reducing the height of the entire filter. In this filter, inside a dielectric block (1), there are disposed inner-conductor-formed holes (2a,2b) in which inner conductors are formed on the inner surfaces of the holes (2a,2b). Coupling electrodes (3a,3b) are arranged on an outer surface of the dielectric block (1) and are electrically connected to the inner conductors. Additionally, the coupling electrodes (3a,3b) are extended, for example, from the edge of an opening surface of the dielectric block (1) which contains the open ends of the inner-conductor-formed holes (2a,2b), onto a side surface which is disposed parallel to a direction in which the inner-conductor-formed holes (2a,2b) are aligned. <IMAGE>
