ABSTRACT:
A dielectric filter can be miniaturized. A dielectric filter comprised of a plurality of dielectric resonators (R.sub.1), (R.sub.2) having a dielectric block (11) with an outer conductor (12) and in which a plurality of through-holes (13), (13) bored through the dielectric block (11) and inner conductors (14) provided within the plurality of through-holes (13), (13) so as to be electrically connected on their one end faces to said outer conductor (12). Recesses (15) are formed on the other end faces of the plurality of through-holes (13) of the dielectric block (11), and electrodes (16) are formed within the recesses (15) so as to communicate with the inner conductors (14) to thereby construct an additional capacitance (Cp).
