Abstract: A solid electrolytic capacitor having an anode body which is punched from aluminum sheet, etched and folded, and provided with a dielectric oxide layer by electrolytic oxidation, which dielectric oxide layer is covered with a semiconducting oxide-layer on which a conducting layer and leads are provided. In order to prevent contamination of the portion of the anode tag 9 to which the lead has to be welded, the anode tag 9 is designed with one or more diversions or branches 124, 25, 27, 29 in and/or out of the original plane, so that one or more apertures or recesses are formed between the relevant diversion or branch and the upper side of the anode body with a projected height of at least 0.8 mm.
