PROBLEM TO BE SOLVED: To provide a cold-rolled steel sheet for a drum can which has particularly proper bake hardenability, has a casting yield, is inexpensive, also has excellent low temperature toughness, has sufficient strength even in retreatment, and is hard to be deformed, and to provide a method of producing the same. SOLUTION: The cold-rolled steel sheet for a drum can has a composition comprising, by mass, 0.0015 to 0.060% C, 0.0015 to 0.060% Si, 0.15 to 0.60% Mn, 0.0015 to 0.060% P, 0.0015 to 0.060% S, 0.015 to 0.060% Al and 0.0015 to <0.0050% N, and the balance Fe with inevitable impurities, and in the C and N, the total of solid solution N and C is 0.0005 to 0.0020%.
