Provided is a resin-coated metal sheet and a production method therefor. The resin-coated metal sheet includes: a metal sheet layer 2; and a resin layer 3 containing a polyester resin and coating a sheet surface of the metal sheet layer 2, in which the resin layer 3 has a melting point of 225° C. to 255° C. and includes: a surface layer 31 located on a surface opposite to a side facing the metal sheet layer 2; a lower layer 33 facing the metal sheet layer 2; and an intermediate layer 32 between the surface layer 31 and the lower layer 33, the surface layer 31 contains a lubricating component composed of a polyolefin having a melting point of 75° C. to 140° C., and a coverage ratio of the lubricating component exposed on a surface of the layer 31 is 0.040% to 0.80%.
