Abstract: PURPOSE: A frequency variable coaxial dielectric resonator is provided to overcome an adjustable bounds of a resonance frequency and achieve an easier manufacturing process. CONSTITUTION: A dielectric member(100) has an inside surface and an outside surface. An inside conductive member(230) is shorter in length than the inside surface of the dielectric member(100). A conductive shaft member(400) is inserted into a through hole, which is formed on a coaxial dielectric resonator, and is capable of change the length to be inserted into the though hole, thereby varying a resonance frequency according to the inserted length. The dielectric member(100) has two end parts and a predetermined longitudinal length. The through hole is formed along a central line from the lower end part to the upper end part of the dielectric member(100) in the direction of the dielectric member(100). The through hole takes preferably a cylinder type, on which a forming method like one axis press is easily applicable.
