<p>Provided is a surface-treated metal plate that has at least two film layers and can be manufactured easily and at low cost using continuous coating equipment for surface-treated metal plates. The interlayer adhesion between one film layer and the film layer immediately therebelow is excellent, and both film layers have good film performance. One or both sides of the metal plate have at least two film layers with different components. This surface-treated metal plate is characterized in that a diffusion layer is formed at the boundary area between an upper first film layer and a second film layer immediately therebelow. The components of the two layers mix in the diffusion layer. If the thickness of the diffusion layer is t and the total thickness of the diffusion layer, the first film layer, and the second film layer is T, then 0.2 ⤠t/T ⤠0.8.</p> |
