摘要： A current collector for an electrochemical element including an aluminum foil showing a peak in the range between 945 cm−1 and 962 cm−1 in measurement of a surface layer of the aluminum foil by Fourier transform infrared spectroscopy. The current collector can be obtained by a manufacturing method which includes the steps of: preparing an aluminum foil material; washing a surface of the aluminum foil material with a chemical solution capable of dissolving aluminum such as hydrochloric acid, aqueous nitric acid, aqueous sulfuric acid, aqueous solutions of alkali metal hydroxides and aqueous solutions of alkaline earth metal hydroxides; and optionally heat treating the aluminum foil at 70 to 200° C. and/or forming a coated layer including an electrically conducive material, on one or both surfaces of the aluminum foil.
