Made of a hot-dip galvanizing layer formed on a surface of at least one of the base material steel plate and the base material steel plate, the hot-dip galvanizing layer is to the surface of the steel sheet, Fe, and the content is more than 0% excess to 5%, Al content is more than 0% and 1.0% or less, and comprises a columnar formed of a ζ phase, and the entire surface of at least 20% of the molten zinc plated layer and the base material steel plate is coated onto the ζ, according to the hot-dip galvanizing layer, a coarse of the ζ grain an interface forming a ζ grains and the base metal steel sheet, and the ζ phase and from 50% or less with respect to the entire interface between the base steel sheet, the base steel sheet, having a specific chemical composition, the base metal steel sheet and the hot-dip galvanizing layer which oxides are present the average grain size of the ferrite is 0 in inside has a fine layer directly in contact with the surface, the average thickness of the fine layer of 0.1 to 5.0㎛, the fine layer of the. 1 to 3.0㎛ and, during the refinement layer containing Si and Mn one or two or more of the oxides, the maximum diameter of the oxide of 0.01 to 0.4㎛ the hot-dip galvanized steel sheet.
