PROBLEM TO BE SOLVED: To provide an aluminum alloy foil for a lithium ion battery positive electrode collector that prevents fracture when manufacturing a battery because it has high elongation, has improved rolling property and achieves the improvement in productivity. ! SOLUTION: An aluminum alloy foil for a lithium ion battery positive electrode collector has a composition containing, by mass%, not less than 1.0% to not more than 1.7% of Fe and not less than 0.05% to less than 0.3% of Mn, and the balance Al with inevitable impurities and has a tensile strength of 200 MPa or more and an elongation of 4.0% or more. !
