    Abstract: An organic resin-covered surface-treated metal sheet having excellent adaptability to producing cans, capable of providing can bodies having excellent hot water-resistant adhering property, providing can lids having excellent adaptability to being formed into lids and having excellent hot water-resistant adhering property, the organic resin-covered surface-treated metal sheet, further, having a surface-treatment coating of the chromium-free type formed by the application treatment exerting small load on the environment and also having advantage in economy. The organic resin-covered surface-treated metal sheet has the surface-treatment coating and an organic resin film on the surface-treatment coating on at least one surface of the metal sheet. The surface-treatment coating contains a poly-carboxylic acid type polymer and a polyvalent metal compound. If the surface-treatment coating is measured for its infrared-ray absorption spectra, a peak height ratio ( β / α ) of a maximum absorption peak height ( α ) in a wave number range of 1660 to 1760 cm -1 and a maximum absorption peak height ( β ) in a wave number range of 1490 to 1659 cm -1 is from 0.05 to 2.35.
