Beschreibung
Zusammenfassung:	An electronic device according to an embodiment of the disclosure includes a housing that forms a portion of an outer surface of the electronic device and a display disposed in the housing and visually exposed through one side of the housing. The housing includes a first portion containing a metallic material, and the first portion includes a base material layer made of the metallic material, a first film layer that is disposed adjacent to a surface of the housing and that contains oxide of the metallic material, and a second film layer that is disposed between the base material layer and the first film layer and that contains oxide of the metallic material. The first film layer includes a first pore structure that extends in a direction perpendicular to a surface of the first film layer, and the second film layer includes a second pore structure that is partially in fluid communication with the first pore structure and that extends in a radial shape toward the base material layer.
