Abstract
This plated steel material includes a steel sheet, a plated layer formed on the steel sheet, and an oxide layer formed on the plated layer, in which the plated layer has a chemical composition containing, by mass %, 1.0 to 60.0% of Al, 1.0 to 15.0% of Mg, 0 to 2.0% of Si, 0 to 2.0% of Ca, and 0 to 2.0% of Fe, and a remainder being of Zn and impurities, the oxide layer has a thickness of 5 nm or more, and a (Al+Mg)/Zn intensity ratio that is the ratio of the total of the maximum intensity of Al and the maximum intensity of Mg to the maximum intensity of Zn in energy dispersive X-ray analysis of the oxide layer is 1.0 or more, and the oxide layer includes an amorphous microstructure.
