ABSTRACT:
In a dielectric filter according to the present invention, a depressed part is formed by removing a portion of an outer peripheral conductor on the open face side of each of a plurality of one-end face short-circuited type coaxial resonators or a portion of the outer peripheral conductor including a dielectric member. A dielectric substrate having a plurality of capacitance forming electrodes for forming antiresonance capacitances between the electrodes and inner peripheral conductors of the coaxial resonators formed thereon is mounted on the depressed part, and a reactance element for coupling the capacitance forming electrodes is provided on the dielectric substrate.
