ABSTRACT:
A fused solid electrolytic capacitor comprises a cathode part formed by applying a first external conductive layer on the solid electrolyric capacitor element, connecting a fuse wire to the first external conductive layer, applying, in turn, an insulating resin layer and a second external conductive layer onto the solid electrolytic capacitor element so that an electrical bridge is formed between the first and second external conductive layers of the solid electrolytic capacitor through the fuse wire which is connected to the first external conductive layer and then electrically connecting the second external conductive layer and the external cathode terminal. According to such a capacitor structure, the fuse wire would not be broken due to, for instance, vibration, the reliability of connection of the fuse wire and yield of the capacitor are markedly improved since the fuse wire is firmly fixed. Further, the production processes can be simplified and after incorporating the fuse into the element, the capacitor can be produced according to the production lines common to those for capacitors in which any fuse is not incorporated.
