Abstract

An object of the present invention is to provide an aluminum alloy foil for an electrode current collector, the foil having a high strength after the drying step while keeping a high electrical conductivity. Disclosed is a method for manufacturing an aluminum alloy foil for electrode current collector, including: maintaining an aluminum alloy ingot comprising 0.1 to 0.5% of Fe, 0.01 to 0.3% of Si, 0.01 to 0.2% of Cu, 0.01% or less of Mn, with the rest being Al and unavoidable impurities, at 550 to 620° C. for 1 to 20 hours, and subjecting the resulting ingot under a hot rolling with a starting temperature of 500° C. or higher and an end-point temperature of 255 to 300° C.
