Abstract
This plated steel sheet includes a base steel sheet, a plated layer formed on a surface of the base steel sheet, and an oxide film formed on a surface of the plated layer, the plated layer has a chemical composition containing Sc: 0.000010 to 4.0% in mass %, and has a cross section, in the thickness direction, in which the area fraction of an intermetallic compound phase containing Sc and having an equivalent circle diameter of 5.0 μm or less is 0.1 to 10.0%, and the oxide film has a thickness of 10 nm or more.
