PROBLEM TO BE SOLVED: To provide a road stud with excellent visibility.SOLUTION: A road stud includes a body and a reflection member having retro-reflect ability of light provided on the side face of the body, and glass beads are embedded in a top face of the body and a part of the glass bead is exposed. Light irradiated to the road stud from its side is retro-reflected to an irradiation direction by a reflection member so that visibility from the side of the road stud is improved. Light irradiated to the road stud from above or from obliquely above it enters the inside from an exposed part of the glass bead and is retro-reflected to the irradiation direction, by exposing at least a part of the glass bead. Thus, the visibility of the road stud not only from the side part thereof but also from above or obliquely above it. |
