PROBLEM TO BE SOLVED: To provide a rolling method and the like by which plated steel sheets for cans, of materials different in hardness, elongation, tensile strength or the like can be manufactured for each material and also steel sheets having various surface states can be manufactured for each surface state by making the temper rolling at wide rolling rate possible by eliminating the problem of jumping in wet temper rolling. SOLUTION: When performing the wet temper rolling after tandem cold rolling or reverse cold rolling of the steel sheet, rolling rolls on the surface of which many minute hollows having a diameter of 60-250μm, a depth of 2-250μm and a height of swollen part around the hollow of≤5μm are formed at the pitch of 80-1,500μm are used for rolling in the final cold rolling, thereby the rolling stability of the steel sheet when subjected to the wet temper rolling after the cold rolling is improved.
