To provide an Al-coated steel sheet that is improved in total reflection characteristics, corrosion resistance, and appearance after subjecting to an anodizing treatment. [Means for Resolution] An Al-coated steel sheet containing a base steel sheet having on a surface thereof an Al-coated layer having an average thickness of 7 µm or more with an Al-Fe-Si based alloy layer intervening therebetween, a surface layer portion of the Al-coated layer extending from the surface thereof to a depth of 3 µm having an average Si concentration of 2.0% by mass or less, and preferably 1.3% by mass or less, and an area ratio of an Al-Fe based intermetallic compound phase occupying the surface of the Al-coated layer being 10% or less. |
