PURPOSE: A road stud is provided to have excellent visibility by increasing the reflective brightness of a reflector and to reduce the manufacturing cost by using a solid reflector which is easy to manufacture. CONSTITUTION: The road stud contains: an anchor buried under the road; a head(12) installed on the anchor to be projected to the road surface; and a reflector(13) composed of a fixed plate(130) attached to the side of the head(12), and many reflection units(131) unified with the fixed plate(130) and provided with three reflective planes to reflect the light by the reflective planes. The reflector(13) is made with transmittable materials such as glass or transparent synthetic resins and mixed with pigments to light up in specific color if necessary.
