SOLID ELECTROLYTIC CAPACITOR ELECTRODE FOIL, METHOD OF PRODUCING IT AND SOLID ELECTROLYTIC CAPACITOR

摘要

An aluminum electrode foil for a solid electrolytic capacitor enhanced in withstand voltage and heat resistance at a cut end without reduction in an effective area of this electrode foil, a method of producing this electrode foil and a solid electrolytic capacitor using this electrode foil. A method of producing an electrode foil for a solid electrolytic capacitor comprising forming a porous skin membrane (11) 5 to 100 times as thick as a barrier skin membrane (3) formed on the surface of the electrode foil (10) on a cut end (5) of the electrode foil (10).
