1. An aluminum member consisting of:
a mother material containing aluminum or an aluminum alloy; and
an anodic oxide film on a surface of the mother material, wherein a thickness of the anodic oxide film is 6 to 100 μm, wherein
an arithmetical mean roughness Ra, a mean length of roughness curve elements RSm, and a Hunter whiteness of the aluminum member, measured from a surface side of the anodic oxide film, are 0.1 μm or more, 10 μm or less, and 60 to 90, respectively, wherein the surface side of the anodic oxide film is opposite a side of the anodic oxide film on the surface of the mother material.
