Summary:A dielectric filter with an attenuation pole having sharp attenuation characteristics. The dielectric block employed in the present dielectric includes a dielectric block single-block formed of TiO2 or BaO, for example. The dielectric block of this type has a plurality of resonators extending from a top surface toward a bottom surface thereof, a plurality of adjusting patterns provided over the top surface thereof, an outer conductor formed by side surfaces and the bottom surface thereof, input and output electrodes, wherein the adjusting patterns, the outer conductor, input and output electrodes maybe plated, for example, by silver, and an insulated cable which may have one end connected to the outer conductor and another end connected to the output electrode is disposed over the plurality of resonators so as to be coupled thereto.
