Plated Steel Sheet

Abstract: [Problem] To more reliably suppress LME and blow hole formation, while maintaining superior corrosion resistance. [Solution] A plated steel sheet according to the present invention has a steel sheet that serves as a base material, a plating layer that is located on at least one section of the surface of the steel sheet, and an oxide layer that is located on the surface of the plating layer, wherein the chemical composition of the plating layer comprises a prescribed component or components, the remainder consisting of Zn and unavoidable impurities, and when a location that is at a depth of 5 nm from the most superficial surface of the oxide layer is observed by X-ray photoelectron spectroscopy (XPS), the intensity ratio ([Al–O]+[Mg–O])/[Zn–O] which is calculated from the intensities of the peaks respectively attributed to Al–O bonds, Mg–O bonds, and Zn–O bonds has a value of 5.0 or greater.
