A cable duct and a manufacturing method thereof are provided to prevent direct/indirect interference of the light by preventing discoloration of a cable duct. A cable duct includes a fixing unit(11) and a sidewall part(12). The fixing unit is installed in the installation place where the cable passes. The sidewall part is curve-cut in both sides of the fixing unit. A light absorption layer is formed in the surface of the sidewall part and the fixing unit. The light absorption layer absorbs the peripheral light and does not reflect the light. An attachable cover(13) is installed in an upper end of the sidewall part. The light absorption layer is formed in the cover. The light absorption layer is implemented by using pigment and a recycled waste. The surface of the light absorption layer is flatted. The light absorption layer is implemented by coating the black paint on the surface of the cover, the fixing unit, and the side wall. |
