PROBLEM TO BE SOLVED: To provide a polyester resin-laminated metal sheet which is excellent in the pouring-off of contents, excellent in adhesion with a metal sheet, heat resistance and formability, and suitable as a material for lids and bodies of metal cans which are manufactured by forming processings such as draw forming and forming by ironing. SOLUTION: The resin laminated metal sheet for container comprises a biaxially oriented polyester resin covering both surfaces of a metal sheet, wherein the resin layer that is to become the container inside after the shaping into a container consists of resin layer(s) of a single layer or plural layers mainly composed of a polyester, in which the resin layer contains 0.1-2.0% by mass of a wax component (in the case of plural layers, each layer containing 0.1-2.0% by mass of a wax component), and in which the resin layer surface after the shaping into the container and the retort treatment has an intensity ratio by the Laser-Raman method, I<SB>2968</SB>/I<SB>3085</SB>, in the range of 0.2≤I<SB>2968</SB>/I<SB>3085</SB>≤1.0 (wherein I<SB>2968</SB>indicates a Raman band intensity near 2,968 cm<SP>-1</SP>and I<SB>3085</SB>that near 3,085 cm<SP>-1</SP>).
