To further suppress the occurrence of LME and paint film blistering during welding. A plated steel sheet according to the present invention includes on at least a part of a surface of a steel sheet, a plating layer having a chemical composition containing, by mass %, Al: 30.00 to 70.00%, Mg: 7.00 to 20.00%, Fe: 0.01 to 15.00%, and selectively containing one or two or more elements selected from the group consisting of an element group A to an element group G with a balance composed of 5.00 mass % or more of Zn and impurities, wherein: in a surface structure of the plating layer, an average area ratio of an α/τ lamellar structure being a metal structure in which rod-shaped α phases are dispersed in a τ parent phase is 30% or more and 95% or less; and in a measured result obtained by measuring the plating layer by an X-ray diffraction method, an intensity ratio I220/I111 of an intensity I220 of a peak corresponding to a (220) plane of the α phase to an intensity I111 of a peak corresponding to a (111) plane of the α phase is 0.25 or more.
