Abstract
An easily and inexpensively producible surface-treated metal plate which uses a continuous coating facility for a surface-treated metal plate to provide at least two coating layers. A surface-treated metal plate comprised of a metal sheet on one surface or both surfaces of which two or more coating layers of different ingredients of formulation are provided, which surface-treated metal plate is characterized in that a diffusion layer is formed at an interface part between a first coating layer as a top layer and a second coating layer directly under the first coating layer, wherein the ingredients of the first coating layer and the second coating layer are mixed in the diffusion layer, and in that t/T is 0.2≦t/T≦0.8 where a film thickness of said diffusion layer is 't' and a total film thickness of said diffusion layer, said first coating layer, and said second coating layer is 'T'.
