    摘要： A method for manufacturing a cold rolled steel sheet for use in a shadow mask is disclosed, in which without adding an expensive alloy element, a short intermediate decarburization annealing is carried out, and despite this fact, a forming defect does not occur after the forthcoming stacked annealing. The method includes the steps of preparing a steel composed of, in weight %, 0.003% or less of C, 0.10-0.20% of Mn, 0.01-0.05% of Al, 0.004% or less of N, and a balance of Fe and other unavoidable impurities. A hot rolling is carried out on the steel at a temperature of above 910° C., and then, a first cold rolling is carried out to form a first cold rolled steel sheet. Then a decarburization is carried out on the first cold rolled steel sheet down to a carbon content of 0.0015% to form a decarburized steel sheet, and then a second cold rolling with a reduction ratio of more than 35% is carried out on the decarburized steel sheet.
