A case frame used in various devices and a method of manufacturing the case frame are provided. The method includes forming the case frame in a shape corresponding to a product to which the case frame is applied, forming a first painting layer with a color of a material applied to a surface of the formed case frame, depositing a transparent oxide deposition layer having a refractive index on an upper portion of the first painting layer, and forming a second painting layer on an upper portion of the transparent oxide deposition layer. Accordingly, the case frame can have an excellent texture by reproducing a brightness and a color anisotropy on the basis of a viewing angle by adding only a simple manufacturing process, thereby being able to improve quality of an electronic device in general and to promote a user's desire for purchasing the device.
