Abstract
The present disclosure provides a high-quality electrolytic aluminum foil which includes a smooth surface and an end portion containing no dendritic deposit, and a method for producing the same which can obtain the electrolytic aluminum foil at a high collection rate. An electrolytic aluminum foil of the present disclosure includes a surface having an arithmetic average height (Sa) of 0.15 μm or less, wherein when, for a size of a crystal grain present in a cross-sectional surface, a first maximum dimension as measured in a thickness direction of the cross-sectional surface is x (μm), and a second maximum dimension as measured in a width direction of the cross-sectional surface is y (μm), x and y satisfy (x+y)/2≤3 μm and 1≤x/y≤4.
