Plated Steel Sheet
Abstract: Provided is a plated steel sheet having high LME resistance. A plated steel sheet according to the present invention is characterized by having a prescribed chemical composition and is characterized in that: when the C-concentration is measured by GDS in the depth direction of a base steel sheet starting from the interface between the base steel sheet and a plating layer, the depth at which the C-concentration is 0.05% or less is 10 µm or more; the thickness of a layer where the area percentage of a ferrite phase is 90% or more is at least 20 µm in the depth direction from the surface of the base steel sheet; and the roughness expressed as Ra of the interface between the base steel sheet and the plating layer is 3.0 µm or less.
