PURPOSE: A high-manganese galvanized steel plate and a manufacturing method thereof are provided to obtain a galvanized steel plate with superior platability and coating adhesion by employing a high-manganese steel substrate. CONSTITUTION: A high-manganese galvanized steel plate comprises C of 0.1-1.5weight%, Mn of 5-35weight%, Si of 0.1-3weight%, Al of 0.01-3weight%, and Fe and inevitable impurities of the remaining amount. A Mn-Ni-Fe-Al-Si-Zn alloy phase is formed in the interface between a galvanized layer and a steel substrate. A manufacturing method of the galvanized steel plate comprises the steps of: coating a steel sheet with Ni, annealing the coated steel sheet, and dipping the annealed steel sheet.
