Provided are: an aluminium alloy foil having excellent moldability; and a production method for aluminium alloy foil. The aluminium alloy foil has a composition containing 1.0% to 1.8% by mass Fe, more than 0.10% but no more than 0.20% by mass Si, 0.005% to 0.05% by mass Cu, and no more than 0.01% by mass Mn, with the remainder being made up of Al and unavoidable impurities. In crystal orientationanalysis per unit of area by backscattered electron analysis, for crystal grains surrounded by the large angle grain boundary which is the grain boundary at which difference in orientation is at least 15 degrees, average particle size does not exceed 10 [mu]m, maximum particle size/minimum particle size <= 3.0, and stretching in directions of 0 degree, 45 degrees and 90 degrees with respect to the direction of rolling when foil thickness is 30 [mu]m is at least 25% in each direction.
