To provide a reflection body to be attached to supporters, which performs retroreflection concerning each vehicle coming from each direction of a route and is easily attached to the supporters, etc., by setting the reflection luminance at an efficient angle.

Reflection surfaces 4 (41, 42 and 43) which are attached to a supporter 3 of a road equipment, etc., and whose main body front surfaces are turned to the respective directions of the route are formed by multiple retroreflection groups 4a and 4b, etc. Reflection luminance is enhanced to permit the respective retroreflection groups 4a, 4b, etc., to be turned to one direction in light axis. The rear surface side of the main body surfaces is formed to be a recessed surface shape to interpolate the curved surface of the supporter so that so that the reflection body is stably fixed.
