Abstract

PURPOSE: To easily obtain an etched foil excellent in mechanical strength without reducing its surface-enlarging magnification, by performing the treatment of etching an Al foil useful as the electrode of a capacitor while applying many fine lines onto the surface of said foil.
CONSTITUTION: Many fine lines 2 resistant to corrosion are applied onto the surface of an Al foil in parallel with each other, for instance, along the logitudinal, i.e. rolling, direction of the foil 1, and the etching treatment is performed under this condition. Hence, an etched surface having many deep rugged parts where a dissolution amount is large is formed on the surface part onto which the lines 2 are not applied, while an etched surface having many shallow rugged parts where either dissolution is not brought about or a dissolution amount is small is formed on the part onto which the lines 2 are applied. By this constitution, tensile strength along the rolling direction of the foil and bending strength along a direction perpendicular to said rolling direction are made large.
