Abstract
An aluminum alloy foil having a composition, including Fe: 1.2% by mass or more and 1.8% by mass or less, Si: 0.05% by mass or more and 0.15% by mass or less, Cu: 0.005% by mass or more and 0.10% by mass or less, and Mn: 0.01% by mass or less, with a remainder being Al and inevitable impurities. An average crystal grain size of the aluminum alloy foil is 20 to 30 μm, a maximum crystal grain size/the average crystal grain size is ≤3.0, a Cube orientation density is 5 or more, a Cu orientation density is 20 or less, and an R orientation density is 15 or less.
