An aluminum alloy foil (1) is an aluminum alloy foil having a first surface (1A). The aluminum alloy foil (1) contains: aluminum; silicon; 0.4-3.04 mass% of manganese; 0.03-0.08 mass% of iron; 0.00001-0.03 mass% of zinc; 0.00001-0.02 mass% of copper; and 0.00001-0.01 mass% of magnesium. In the aluminum alloy foil (1), the total content of silicon and iron is 0.1 mass% or less. In the aluminum alloy foil (1), the mass ratio of manganese relative to the total mass of silicon and iron is 7.0 or more. On the first surface (1A), the area ratio of second phase particles having a circle-equivalent diameter of 1.5 [mu]m or more is 0.1% or less. 铝合金箔(1)是具有第一面(1A)的铝合金箔。铝合金箔(1)包含铝、硅、0.4质量％以上且3.04质量％以下的锰、0.03质量％以上且0.08质量％以下的铁、0.00001质量％以上且0.03质量％以下的锌、0.00001质量％以上且0.02质量％以下的铜、以及0.00001质量％以上且0.01质量％以下的镁。在铝合金箔(1)中，硅和铁的含量的合计为0.1质量％以下。在铝合金箔(1)中，锰的质量相对于硅和铁的合计质量的比率为7.0以上。在第一面(1A)中，当量圆直径为1.5μm以上的第二相粒子的面积率为0.1％以下。
