It includes a base steel sheet and hot-dip galvanizing layer, and a ferrite phase and 50% or less, the hard tissue at least 50% by volume fraction in the range of 1/8 to 3/8 the thickness from the thickness of the base metal steel sheet surface, starting from the interface between the plated layer and the base material steel plate a base material with a volume fraction of the retained austenite volume fraction of 3% or less nitro, hard tissue within the range of the steel sheet to a depth 20㎛ to, 1/8 the thickness to 0.10 to 0.90 times the volume fraction of a base material in the thickness range of 3/8 on the surface of the steel sheet, Fe: 5% or less, Al: 1.0% or less, having a hot-dip galvanizing layer on and through the main-phase crystal containing the ζ phase to at least 20% of the interface between the plated layer and the steel sheet of the base metal steel sheet surface side to have a fine layer, the average grain size of the ferrite in the average thickness of the finer layer, finely divided layer, the maximum diameter of the oxide is individually hot-dip galvanized steel sheet defined as included in the refinement layer.
