Abstract
A laminated metal sheetincludes a filmincluding a laminated resin layer including at least two layers with polyester as a main component formed on one face or both faces of a metal sheet. A polyester resin layer serving as a lower layerin contact with the metal sheetof the laminated resin layer contains 90 mol % or more of terephthalic acid as a polycarboxylic acid component and contains a polyol component containing ethylene glycol and 1,4-butanediol, in which the polyol component contains 30 to 50 mol % of ethylene glycol, 50 to 70 mol % of 1,4-butanediol, and 10 mol % or less of other polyol components. A polyester resin layer serving as an upper layerof the laminated resin layer contains polyester containing terephthalic acid as a polycarboxylic acid component and 1,4-butanediol as a polyol component both of which are 90 mol % or more of the respective components, has a total thickness of 3 to 25 μm, and has a ratio (I011/I100) of peak intensity (I011) observed in the range of 2θ=15.5 degrees to 17.0 degrees to peak intensity (I100) observed in the range of 2θ=22.5 degrees to 24.0 degrees in X-ray diffraction in the range of 0.2 to 5.0.
