Oh method of manufacturing a galvanized steel sheet, a zinc-based plating is performed on the steel sheet, on its surface, as the zinc ion concentration, and containing a zinc ion in the range of 5~100g / l, pH is 4 to 6, the liquid temperature (liquid temperature) is brought into contact with a 20~70 ℃ an aqueous solution, then the mixture was kept 1-60 seconds, carries out the water washing and drying. As the solution containing the zinc, for example, preferably it contains a sulfate of zinc. According to the above method, the surface of the steel sheet, and the average thickness is more than 10nm, it is possible to manufacture the oxide layer containing the zinc as a main component are formed, excellent press-galvanized steel having a moldability and in a short time and stably.
