Abstract
Disclosed is a resin-coated Al sheet with which a drawn and ironed can having a lustrous appearance can be formed. An upper limit of a thickness of an outer surface resin layer which covers an Al surface which becomes an outer surface of the can and has an arithmetical mean roughness (Ra) of 0.5 μm or less with a thickness which falls within a range of 0.02 μm to 6 μm is determined based on an arithmetical mean roughness (Ra) of the Al surface, wherein the upper limit of the thickness of a coating outer-surface resin layer is decreased when the arithmetical mean roughness (Ra) is increased.
