PROBLEM TO BE SOLVED: To provide a chromium-plated steel sheet for a welded can having superior adhesiveness to paint and corrosion resistance as well as superior weldability, even without pretreatment for welding such as mechanical grinding or chemical treatment. SOLUTION: The chromium-plated steel sheet for the welded can has a chromium hydrous oxide provided on a metallic chromium layer on the surface of a steel sheet. The hydrous chromium oxide is formed so as to be 4 to 25 mg/m<SP>2</SP>in terms of metallic chromium, and has impedance in a range of 1 to 6 mΩ, when the steel sheet is welded after having been subjected to painting, printing and baking.
