ABSTRACT:
In a dielectric filter which has a plurality of dielectric resonators of a TM.sub.010 mode or its modified mode, each dielectric resonator has one dielectric solid body disposed in series with a metallic case having top and bottom faces and at least one side face. A conductive film is provided to form the actual current paths on the surface of the ceramic case, and a conductive plate is provided between the dielectric resonators to electrically connect the resonators with each other, whereby a given electro-magnetic combination is caused between the adjacent dielectric resonators so as to provide a dielectric filter having given characteristics.
