To provide a protective fence of which the existence can be easily visually identified at night not only by a driver who travels on a roadway but also by a passer who rides a bicycle travelling on a sidewalk.

A cross rail 2 is provided between a plurality of struts 1, and a reflective material 3 is attached to the opposed surface of the adjacent struts 1. Accordingly, the fence is retro-reflected by the reflective material 3 not only to a head light of a vehicle travelling on the roadway but also a light of the bicycle travelling on the sidewalk. Thus, the passer riding the bicycle also can visually identify the existence of the protective fence P. In addition, since the reflective material 3 is attached along the entire length of the strut 1, the fence can be visually identified not as a mere point-shaped reflective material of a reflector but as an elongated object.
