To provide a floor surface system capable of eliminating a work for providing a luminous material on a floor material for indicating an escape route.

This floor surface system 1 is constituted by connecting a plurality of plate-like flooring materials 2 having finished surfaces 3. The floor material 2 is equipped with an engaging portion 9 for connecting the floor materials 2 together, and the luminous material 4 is provided on a portion which is exposed in a view from the side of the finished surface 3 of the engaging portion 9 in the connected state of the floor materials 2. Since the floor surface system 1 indicates the escape route by the luminous material 4 only by connecting the floor materials 2 together, it can eliminate the work for providing the luminous material 4 on the floor material 2 for indicating the escape route, so as to improve efficiency in the construction work.
