To purpose of the present invention is to obtain high levels of both the adhesiveness between coatings and the glossiness in a multilayer precoated metal sheet produced on a continuous coating line. A precoated metal sheet having a plurality of coating layers on one or both sides of a metal sheet (10), wherein the coating layers include: a coloring coating layer (111) disposed on the metal sheet (10) side, the coloring coating layer (111) containing a coloring pigment; a pigment-enriched layer (123) formed on the coloring coating layer (111), the pigment-enriched layer (123) having a coloring pigment concentration higher than the average coloring pigment concentration in the coloring coating layer (111), and the coloring pigment concentration increasing towards the obverse layer side; a diffusion layer (122) formed on the pigment-enriched layer (123), the diffusion layer (122) having a coloring pigment concentration that decreases towards the obverse surface side; and a clear layer (121) formed on the diffusion layer (122), the clear layer (121) containing no coloring pigment. The ratio d1/d2 between the thickness d1 of the clear layer (121) and the thickness d2 of the pigment-enriched layer (123) is 1.7≤d1/d2≤4.7. |
