The invention discloses a multi-layer composite steel plate with a visible-light response photocatalysis function and a manufacturing method thereof, and belongs to the technical field of environmental-friendly new materials. The multi-layer composite steel plate with the visible-light response photocatalysis function comprises a base material, an anti-corrosion leather film, a prime coat, a visual beautifying coating, a light degradation shielding layer and a visible-light response photocatalysis coating; and by adopting the continuous manufacturing method, a metal-coating steel plate is adopted as the base material, and the anti-corrosion leather film, the prime coat, the visual beautifying coating, the light degradation shielding layer and the visible-light response photocatalysis coating are sequentially deposited on at least one surface of the base material. The color steel plate provided by the invention can produce photocatalysis efficacy under the visible-light response, can beused for purifying air, sterilizing and eliminating nitric oxide, organic matters and bacteria in the air, and has the advantages of capability of utilizing sunlight, low energy consumption, no needof extraly adding reactants and the like.
