ALUMINUM ALLOY FOIL, LAMINATE, METHOD FOR MANUFACTURING ALUMINUM ALLOY FOIL, AND METHOD FOR MANUFACTURING LAMINATE

摘要

An aluminum alloy foil (1) is an aluminum alloy foil having a first surface (1A). The aluminum alloy foil (1) includes: aluminum; silicon; more than or equal to 0.4 mass% and less than or equal to 1.75 mass% of manganese; more than or equal to 0.02 mass% and less than or equal to 0.08 mass% of iron; more than or equal to 0.00001 mass% and less than or equal to 0.03 mass% of zinc; more than or equal to 0.00001 mass% and less than or equal to 0.02 mass% of copper; and more than or equal to 0.00001 mass% and less than or equal to 0.01 mass% of magnesium. In the aluminum alloy foil (1), a total of a content of the silicon and a content of the iron is less than or equal to 0.1 mass%. In the aluminum alloy foil (1), a ratio of a mass of the manganese to a total mass of the silicon and the iron is more than or equal to 7.0. In the first surface (1A), an area ratio of second phase particles each having an equivalent circle diameter of more than or equal to 1.5 µm is less than or equal to 0.1%. An electric resistivity value of the aluminum alloy foil (1) is more than or equal to 3.0 µΩcm and less than or equal to 5.0 µΩcm.
