<P>PROBLEM TO BE SOLVED: To provide a light-accumulating stud which can be used in a place where vehicles frequently tread thereon, and has fine nighttime visibility, while inter-layer peeling is not generated even when a heavy load is applied, and to provide a manufacturing method of the light-accumulating stud. <P>SOLUTION: The adhesive light-accumulating stud integrally includes a light-accumulating layer, where light-accumulating agent densely exists in a thermosetting resin, on the surface-side of the light-accumulating stud, and a white reflection layer, where the light-accumulating agent hardly exists in a thermosetting resin and most of white pigments exist, on the side of light-accumulating stud adhered on a road surface. Shallow recessions enclosed by lattice-shaped ribs are formed on the adhesive surface formed on the side of white reflection layer adhered on the road surface. <P>COPYRIGHT: (C)2011,JPO&INPIT |
