PROBLEM TO BE SOLVED: To provide a self-cleaning type line of sight induction indicating body which is favorable in the scenery and the appearance, and can remove contaminant on the indicating face without accumulating the contaminant. SOLUTION: For inducing line of sight, an undercoat layer 6 by excellent chemical resistant silicone-based paint is formed on an indicating face 3 to be visually recognized by a vehicle driver, and a film 7 containing titanium dioxide as an optical catalyst is formed thereon. By irradiating ultraviolet light to the film 7, titanium dioxide is activated to hydrophilize the surface, so that the contaminant stuck on the surface is washed away by rainfall and the like. |
