摘要：
A dielectric resonant device having function of a dielectric filter and a dielectric duplexer having a desired external coupling capacitance includes a substantially rectangular-parallelepipedal dielectric block provided with inner conductive holes therein, and input-output electrodes on the outer surfaces extending from an open surface thereof. Also, a method is provided for forming input-output electrodes of the dielectric resonant device for obtaining a given external coupling capacitance, in which the input-output electrodes are formed by a cutting tool including cutting edges applied to two outer surfaces of the dielectric block along first conductive film removing lines on the two outer surfaces, extending from the open surface, and a cutting edge applied to the two outer surfaces along a second conductive film removing line connecting the first conductive film removing lines.
