A resin coated metal sheet includes: a metal sheet; and a resin layer formed on at least one face of the metal sheet. A movable amorphous amount of the resin layer measured by a temperature modulated differential scanning calorimeter being 30% to 46%. An intensity ratio I/Ibetween intensity (I) of a peak attributable to a trans structure of methylene groups in polyethylene terephthalate (PET) around 1,096 cmdetermined from laser Raman spectroscopic analysis measured by making a plane of polarization of linearly polarized laser light incident on a thickness direction section of the resin coating layer perpendicularly to a thickness direction and intensity (I) of a peak attributable to a gauche structure of methylene groups in PET around 1,119 cmdetermined from the laser Raman spectroscopic analysis being 1.1 or more and less than 1.5 at a position with a distance of 1 μm from the metal sheet.
