ABSTRACT:
A long-life highly reliable dielectric resonator, a dielectric filter using the dielectric resonator and a dielectric duplexer, in which the heat accumulated in concave portions is dissipated. The dielectric resonator comprises a frame, a column-shaped dielectric resonant element disposed so as to be integral with the frame at ends thereof, the concave portions formed from the external surface of the frame into the dielectric resonant element in the direction of the axis of the dielectric resonant element, a conductor formed on the overall outer surface of the frame including inside the concave portions, and thermal-conducting means inserted in the concave portions.
