PROBLEM TO BE SOLVED: To enable the production of a cold rolled steel sheet for can, having ridging resistance and deep drawability, by specifying the average crystalline grain size of a steel sheet containing specific essential components and also specifying the colony size and the degree of orientational concentration in the colony, respectively. ;SOLUTION: A steel, which has a composition containing, as essential components, 0.0005-0.0150%, by weight, C, ≤0.10% Si, 0.1-0.6% Mn, ≤0.02% each of P and S, 0.015-0.15% Al, and ≤0.02% N and having the balance Fe with inevitable impurities, is used. Moreover, the average crystalline grain size (d) and the average colony size are regulated to ≤35/μm and ≤80μm, respectively, and the degree S of orientational concentration in the colony, represented by S=X20°/X30°, is regulated to ≤0.8, where X30° means the area of colonies where the orientation difference between adjacent crystalline grains is ≤30° and X20° means the area of colonies where the orientation difference between adjacent crystalline grains is ≤20°, among X30°. By this method, a wide range of application ranging from a dry cell inner package can, etc., to various household electrical and potential parts, automobile parts, etc., can be expected.;COPYRIGHT: (C)1998,JPO
