Abstract
An Al-plated steel sheet includes: a base; an Al-plating layer formed on at least one of opposite surfaces of the base; and a surface layer formed on the Al-plating layer, the surface layer containing: ZnO particles; an organic resin; and acetylacetonato in an amount in a range from 10 mass % to 30 mass %, both inclusive, with respect to a total mass of the surface layer. A mean particle size of the ZnO particles is in a range from 0.10 μm to 5.00 μm, both inclusive, and an amount of coating of the ZnO particles is in a range from 0.5 g/m2 to 10.0 g/m2, both inclusive, in terms of metal Zn.
