Abstract
Provided is a tin-plated steel sheet which is more excellent in yellowing resistance in a steel sheet for containers having a film layer containing zirconium without being subjected to a conventional chromate treatment. A tin-plated steel sheet is adopted which has a steel sheet, a tin plating layer located on at least one surface of the steel sheet, and a film layer located on the tin plating layer and containing zirconium oxide and tin sulfide, in which an adhesion amount of the tin-based plating layer is 0.1 g/mor more and 15 g/mor less in terms of the amount of metal Sn, an adhesion amount of the zirconium oxide in the film layer is 0.2 mg/mor more and 50 mg/mor less in terms of the amount of metal Zr, and an adhesion amount of the tin sulfide is 0.1 mg/mor more and 5 mg/mor less in terms of the amount of sulfur.
