Abstract
A dielectric resonator employing TM.sub.010 mode or its variation mode, and including a cavity resonator and a columnar inner dielectric member accommodated within the cavity resonator a region being formed at an end face of the inner dielectric member so as not to contact the cavity resonator, and a resonant frequency adjusting member being adapted to be movable toward or away from the region, thus adjusting the resonant frequency through variation of a capacitance value in a path passing through the columnar dielectric member, the resonant frequency adjusting member, and the cavity resonator.
