1. An electronic device comprising:
a housing including a rear plate including a first surface exposed to an outside of the electronic device, a second surface opposite to the first surface and disposed in the housing, a first region having a first concavo-convex pattern formed therein, and a second region disposed around an edge of the first region and having a second concavo-convex pattern formed therein, wherein the first region and the second region are disposed on the second surface; and
a processor disposed inside the housing,
wherein the rear plate is formed by injection molding using a mold structure such that the first concavo-convex pattern and the second concavo-convex pattern are integrally formed with the rear plate, the mold structure including a third concavo-convex pattern in a shape corresponding to the first concavo-convex pattern and a fourth concavo-convex pattern disposed around an edge of the third concavo-convex pattern and in a shape corresponding to the second concavo-convex pattern, and
wherein a ratio of a first depth of the first concavo-convex pattern and a second depth of the second concavo-convex pattern is set to 1:20 to 1:500 such that the first region has a first light reflectance and the second region has a second light reflectance different from the first light reflectance.
