The present invention is an aluminum electrode foil used in a solid electrolytic capacitor, and provides an electrode foil for a solid electrolytic capacitor, a manufacturing method of this electrode foil, and a solid electrolytic capacitor using this electrode foil having an improved voltage resistance and heat resistance at the cut-end part without causing a reduction in the effective area of the electrode foil. According to the manufacturing method of the electrode foil for the solid electrolytic capacitor according to the present invention, a porous film 11 having a thickness within the range of from about 5 to about 100 times the thickness of the barrier film 3 is formed on the surface of an electrode foil 10, on the cut-end part 5 of this electrode foil 10. In addition, the present invention provides an electrode foil manufactured according to the above described manufacturing method and a solid electrolytic capacitor using this electrode foil. <IMAGE> |
