[Prior Art] In recent years, consumers have become more and more demanding for 3C products. In addition to having more and stronger functions, it also puts higher requirements on the outer casing of the product, such as anti-corrosion, rust-proof, dust-proof, waterproof and anti-finger function. 〇 [0003] In order to achieve an anti-fingerprint function, conventional methods generally apply a coating or solution having anti-fingerprint properties to the surface of the outer casing to form an anti-fingerprint film. However, the paint or solution having anti-fingerprint properties usually contains toxic organic substances, which are disadvantageous to the environment and human health, and the organic substances are usually complicated in structure and difficult to prepare. [0004] SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an environmentally friendly and easy to prepare housing having an anti-fingerprint function. In addition, it is also necessary to provide a method of manufacturing the above casing.

The non-metallic material may include plastic, ceramic, glass, polymer, and the like. The anti-fingerprint layer 13 is a transparent metal oxynitride layer which is formed by vacuum sputtering. The metal oxynitride may be represented by Mx〇y —]^ or ^〇7 — N—-MexOy-N, wherein M and Me are selected from the group consisting of titanium (Ti), aluminum (A1), Si Xi (Si), and chromium. Any of (Cr) and (Zr), and μ and Me are not the same. When Μ and Me are selected from any one of Ti, Si, and Zr, the 7$2乂, when 厘, ^16 is selected from any one of human 1, (: 1', the 7 2 1 5X, that is, the yttrium, Me and 0 atoms form a saturated oxidation state. The anti-fingerprint layer 13 is an amorphous structure having a thickness of 10Q - 5 〇〇 nm compared to coating an anti-fingerprint coating or solution. The anti-fingerprint layer 13 is formed by vacuum sputtering, and the adhesion of the anti-fingerprint layer 13 to the surface of the substrate 11 is greatly enhanced, in addition to being environmentally friendly and easy to prepare. In addition to the anti-fingerprint function, the N element in the anti-fingerprint layer 13 can also enhance the compactness of the anti-fingerprint layer 13, thereby also making the anti-fingerprint layer 13 have better resistance to corrosion resistance. 099125763 Form number AOiOl 0992045212-0 [0015] It is to be understood that the housing 10 may further include a color layer disposed between the base 11 and the anti-fingerprint layer 13, the color layer for reinforcing the housing 1〇 The method for fabricating the above casing 10 according to a preferred embodiment of the present invention includes the following steps: [001 8] A substrate 11 is provided, and the substrate 11 is pretreated.
