Abstract
Provided is a resin-coated metal sheet that, even when used in a DI can, ensures excellent removability for various contents and stably satisfies various properties required of container material. A resin-coated metal sheet comprises: a metal sheet; and a coating layer of a resin containing a polyester resin as a main component, on at least one surface of both surfaces of the metal sheet, wherein the coating layer has a thickness of 21 μm or more and 38 μm or less, contains 0.01 mass % or more and 2.00 mass % or less of a wax compound, and has a surface indentation modulus of 2000 MPa or more and 3400 MPa or less.
