Abstract
An aluminum member includes: a substrate formed of aluminum or an aluminum alloy that contains 0 to 10% by mass of magnesium, 0.1% by mass or less of iron, and 0.1% by mass or less of silicon and a balance of which is aluminum and unavoidable impurities; and an anodic oxide coating formed on a surface of the substrate. A surface of the substrate on the anodic oxide coating side has an arithmetical mean height Sa of 0.1 to 0.5 μm, a maximum height Sz of 0.2 to 5 μm, and an mean width of roughness profile elements Rsm of 0.5 to 10 μm, where the arithmetical mean height Sa, the maximum height Sz, and the mean width of roughness profile elements Rsm are measured after the anodic oxide coating is removed.
