Beschreibung
Zusammenfassung:	An electronic device according to various embodiments disclosed herein comprises a display and a housing adjacent to the display, wherein at least a portion of the housing includes: an aluminum alloy layer processed into a specified shape; a first film layer formed on the aluminum alloy layer; and a second film layer which is formed between the aluminum alloy layer and the first film layer and in which a plurality of snow flake structures formed adjacent to the first film layer are arranged. The first film layer is formed by a first anodizing process using a first voltage on the aluminum alloy layer, and the second film layer is formed by a second anodizing process using a second voltage on the aluminum alloy layer after the first anodizing process.
