PROBLEM TO BE SOLVED: To provide a dielectric filter which is superior in mass productivity by reducing the size and the number of the item parts. SOLUTION: Dielectric resonators 1, respectively provided with a dielectric substrate 1a, an outer conductor 1d provided on the outer side surface of the substrate 1a, inner conductor 1c provided on the inner side surface of the substrate 1a, a connecting conductor provided on one end face of the substrate 1a and connecting the conductors 1d and 1c and a conductor for connection 1f provided on one surface of the outer side surface and free of electrical contact with each conductor, are provided by at least one in number. Then, the resonators 1 are arranged on an insulated substrate 2 to electrically connect to the electrode 6 provided on the substrate 2 with the conductor 1f to constitute a dielectric filter. |
