PURPOSE: A dielectric is provided to prevent the emission of an electromagnetic wave, and to block the influence of the other electromagnetic wave. CONSTITUTION: A dielectric filter includes a dielectric body for separating electric polarization by an electric field, and a conductor coating plated on the surface of the dielectric body. The dielectric filter comprises: an upper resonance hole and a bottom resonance hole, divided by section in the upper and low sides by standardizing the center part, after being pierced and molded in the length direction of the dielectric body; a trim section for having the predetermined capacitance value by being grindingly processed in a ring shape in the inner side of the center part, dividing the upper part resonance hole and the bottom part resonance hole; an input terminal and an output terminal for grindingly processing the conductor coating, located in the outer side of the dielectric body in the opposite direction with the upper and low sides of the trimsection.
