PROBLEM TO BE SOLVED: To provide a dielectric resonator capable of eliminating losses on the dielectric of a shielding void surface and respectively individually changing a non-load Q and a frequency by arranging one surface, where the electrode is formed of a dielectric column on the inner surface of a shielding void. ;SOLUTION: For a dielectric filter 1, the dielectric column 2 is arranged inside a metallic shielding void 5. For the dielectric column 2, the electrodes 3 and 4 are formed on the opposing two surfaces. The dielectric column 2 is arranged, so as to bring the electrode 4 into contact with the inner side bottom surface of the shielding void 5 and electrically connected and fixed to the shielding void 5. The electrode 3 faces the inner side ceiling surface of the shielding void 5 at fixed intervals. When high-frequency signals are inputted from a coaxial connector 6 attached to the side wall of the shielding void 5, an electric field is generated between the electrodes 3 and 4, a magnetic field is generated along the circumference of the dielectric column 2, an electromagnetic field is concentrated and confined inside the dielectric column 2, and the dielectric column 2 functions as the dielectric resonator.;COPYRIGHT: (C)1998,JPO
