PROBLEM TO BE SOLVED: To obtain a resin coated metal sheet for a container excellent in the takeout properties of content, the adhesion with a metal sheet, heat resistance, molding processability, etc. SOLUTION: The resin film becoming the inner surface side of the container comprises a resin layer based on a polyester and contains 0.1-30 mass% of a hydrophobic polymer with respect to the resin layer. Further, in order to set the distribution state of the hydrophobic polymer in the resin film to a proper range, the surface of the resin layer after the container is molded using the resin film and subjected to retort treatment is set so that a Raman band intensity ratio I<SB>2968</SB>/I<SB>3085</SB>is 0.10-1.0. Herein, I<SB>2968</SB>is the Raman band intensity in the vicinity of 2,968±5 cm<SP>-1</SP>originating from the C-H expansion and contraction of the glycol component of the polyester resin due to a laser Raman spectral method and I<SB>3085</SB>is the Raman band intensity in the vicinity of 3,085±5 cm<SP>-1</SP>originating from the C-H expansion and contraction of the benzene ring of the polyester resin due to the laser Raman spectral method.
