| Zusammenfassung: | To provide an aluminum alloy foil that can suppress the breakage during production, and to provide a method for producing the same.SOLUTION: The aluminum alloy foil of the present invention contains Cu: 0.05 mass% or more and 0.2 mass% or less, Mn: 1.0 mass% or more and 1.5 mass% or less, and the balance is Al and unavoidable impurities. This aluminum alloy foil has a tensile strength of 240 MPa or more and less than 280 MPa, an elongation of 3% or more, and an interval of large-angle crystal grain boundary in the thickness direction of 0.5 μm or less.SELECTED DRAWING: Figure 1
