Abstract: Interior materials are attached to an outer surface of a plastic injection mold and expose, to outside, light selectively emitted from a light source arranged in the plastic injection mold. The interior materials include a wood pattern layer formed of natural wood and having a plurality of first lighting holes through which the light passes, a light block layer coupled to a rear surface of the wood pattern layer, blocking light, and having a plurality of second lighting holes formed therein corresponding to the plurality of first lighting holes, and a touch sensor electrode coupled to a rear surface of the light block layer. As texture of natural wood is embodied on the surface of the interior materials, and the surface of interior materials emits light and simultaneously, an operation of a preset function in the interior materials may be controlled by touching the surface of interior materials.
