Abstract
A dielectric filter has an electroconductive case, dielectric resonators each having electrodes formed on the opposite sides thereof disposed inside of the case, a ground plate disposed inside of the case, and external connectors. At least one of the electrodes is a thin film multilayered electrode connected to the ground plate. The ground plate is provided with protuberant portions, and each of the protuberant portions is connected, at the lower surface portion of the protuberant portion, to the respective thin film multilayered electrode on a corresponding dielectric resonator. The lower surface of the protuberant portion is smaller than the size of the corresponding dielectric resonator defined by the side edges thereof.
