Abstract
A delay line device for delaying signal transmission. A lamination comprises an uppermost grounding electrode, a lowermost grounding electrode, a plurality of strip-line conductors, a plurality of intermediate grounding electrodes, dielectric layers, and protective layers. The strip-line conductors and the intermediate grounding electrodes are accumulated alternately and are interposed between the uppermost and the lowermost grounding electrodes. The dielectric layers are each interposed between each adjacent pair of the strip-line conductor and the intermediate grounding electrode. The protective layers are respectively provided on outer surfaces of the uppermost and the lowermost grounding electrodes. The strip-line conductors are connected via a through hole to form a strip-line conductor series and both ends of the series are extended onto a side surface of the lamination. An external input electrode is connected to one of the ends of the strip-line conductor series on the side surface of the lamination. An external output electrode is connected to the other end of the strip-line conductor series on the side surface of the lamination. An external grounding electrode is connected to connecting portions of the uppermost, lowermost and intermediate grounding electrodes on the side surface of the lamination.
