Beschreibung
Zusammenfassung:	According to various embodiments of the present invention, an electronic device comprises: a display; a housing including the display. At least a part of the housing includes: an aluminum alloy processed into a designated shape; a first film layer formed on the aluminum alloy; and a second film layer formed between the aluminum alloy and the first film layer. The first film layer is formed by a first anodizing process using a first voltage for the aluminum alloy. The second film layer can be formed by a second anodizing process using a second voltage for the aluminum alloy after the first anodizing process. Therefore, the quality can be controlled in a stable manner. 본 개시의 다양한 실시예들에 따른 전자 장치는, 디스플레이; 및 상기 디스플레이를 포함하는 하우징으로서, 상기 하우징의 적어도 일부는 지정된 형상으로 가공된 알루미늄 합금; 상기 알루미늄 합금 상에 형성된 제1 피막층; 및 상기 알루미늄 합금 및 상기 제1 피막층 사이에 형성된 제2 피막층을 포함하는 상기 하우징을 포함하고, 상기 제1 피막층은 상기 알루미늄 합금에 제1 전압을 사용한 제1 아노다이징 공정에 의해 형성되고, 상기 제2 피막층은 상기 제1 아노다이징 공정 후, 상기 알루미늄 합금에 제2 전압을 사용한 제2 아노다이징 공정에 의해 형성될 수 있다.
