The invention refers to a solid electrolytic capacitor, the anode and cathode leads of which are in known manner formed from a metal strip while the electrolytic capacitor per se comprises a metallic anode body which has a relatively large plane surface above which a dielectric layer and a cathode layer are stacked in that order. The cathode lead is a part formed from the metal strip and shaped as a plate having a surface that is at least as large as the plane surface of the anode body and faces the cathode layer.
