A delineator easily recognized by the driver even when attached at a moderate curve of a road includes colorless transparent reflectors attached inclined by a prescribed angle with respect to an aluminum base and amber transparent reflectors attached inclined in the opposite direction. Each reflector has a reflex reflecting element, an optical axis of which is inclined in the same direction as the corresponding reflector. Thus light beams entering in a direction parallel to the surface on which the delineator is attached can also be reflected.
