Abstract

An aluminum member includes: a base material made of aluminum or an aluminum alloy; and an anodized coating including a barrier layer on a surface of the base material and a porous layer on the barrier layer, wherein the anodized coating contains phosphorus (P) and sulfur (S), and has a thickness of 100 μm or less, and, in a depth direction heading from a surface of the anodized coating toward the base material, a depth providing a maximum content of S in a region situated at a depth of 500 nm or more from the surface of the anodized coating is larger than a depth providing a maximum content of P, and an inequality (the maximum content of S)>(the maximum content of P) holds.
