Plated steel sheet
Provided is a plated steel sheet comprising a base steel sheet and a plating layer formed on a surface of the base steel sheet, wherein the plating layer has a predetermined chemical composition, and when measuring the plating layer by glow discharge spectroscopy (GDS), a ratio of “Al concentration at center of plating layer”/“Al concentration at position of plating layer where Fe concentration is 50% of base steel sheet” is 0.10 to 1.50.
