The present application relates to the technical field of electronic equipment, and specifically discloses a casing, comprising: a base material, including an outer surface, and a through hole penetrating the outer surface is formed on the base material, a target area is arranged on the periphery of the through hole, and the target area is The corresponding L value in the Lab color model is 20-30; the anti-reflection layer is arranged in the target area on the substrate, and the corresponding L value in the Lab color model of the target area where the anti-reflection layer is arranged is 5-15 . In the above manner, the corresponding L value of the target area on the surface of the housing of the present application in the Lab color model is reduced to 5-15, which meets the user's requirements for the surface appearance of the electronic device. |
