Electronic device and method for manufacturing housing of electronic device

An electronic device comprising:

• a housing at least partially including an electrically conductive material,
• wherein a surface of the electrically conductive material includes an oxide film layer including a plurality of cavities,
• wherein each of the plurality of cavities are entirely filled with a first colorant having a first color and a second colorant having a second color different from the first color, and
• wherein, within each of the plurality of cavities, the second colorant is deposited on the first colorant,
• wherein the surface of the electrically conductive material has a hardness of 240 to 320 HV (Vickers hardness), an arithmetical mean roughness (Ra) of 0.03 to 0.04 μm, and a maximum height roughness (Rz) of 0.32 to 0.45 μm.
