ABSTRACT OF THE DISCLOSURE A method for manufacturing a zinciferous electroplated steel sheet excellent in press-formability, which comprises the steps of: electroplating a steel sheet in a zinciferous acidic electroplating solution, which contains nitric acid ions or nitrous acid ions in an amount within a range of from 0.1 to 50 g per liter of the electro- plating solution, and oxide particles of a metal or a semimetal, uniformly dispersible into the electroplating solution, in an amount within a range of from 0.1 to under 0.5 g per liter of the electroplating solution, to form, on at least one surface of the steel sheet, a zinciferous electroplating layer in which zinc hydroxide particles having the oxide particles as nuclei thereof are uniformly dispersed.
