Abstract
An aluminum alloy foil includes: aluminum; silicon; manganese; iron; zinc copper; and magnesium. In the aluminum alloy foil, 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, 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, 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 is more than or equal to 3.0 μΩcm and less than or equal to 5.0 μΩcm.
