Resin coated metal sheet for container

A resin coated metal sheet for a container, the resin coated metal sheet comprising:

• a polyester resin coating layer in which 90 mol % or more of structural units are ethylene terephthalate units, the polyester resin coating layer being a biaxially stretched film,
• wherein a half-value width of a peak attributable to C=O stretching vibration around 1,730 cm−1 determined 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 polyester resin coating layer perpendicularly to a thickness direction is:
• 18.5 cm−1 to 22.0 cm−1 at a position with a thickness of 1.0 μm from a metal sheet side of the polyester resin coating layer, and
• greater than 17.0 cm−1 and 18.5 cm−1 or less at a position with a thickness of 1.0 μm from a surface side of the polyester resin coating layer.
