In addition, since a large number of cut surfaces of the heat conductive rubber particles are exposed on the surface layer portion to form a mosaic pattern, it has an excellent aesthetic appearance. Reference FIG. 1 shows the above “Δ” state, and Reference FIG. 2 shows the above “X” state. As particularly shown in Reference FIG. 1, many cut surfaces of the heat conductive rubber particles are exposed in the surface layer portion.

る。また、施工時に裁断することも容易である。As described above, according to the present invention, since both the base portion and the surface layer constituting the rubber tile are made of vulcanized rubber, it is possible to absorb some unevenness and unevenness of the base. In addition to being easy to carry out, the walking feeling and safety are higher than those of conventional flooring made of natural stone and artificial stone, and you can walk with peace of mind. Also, it is easy to cut at the time of construction.

模様が自動的に得られる。Moreover, since the heat conductive rubber particles are dispersed in the surface layer portion, the surface layer portion has high heat resistance,
Quickly spreads heat in the lateral direction. Therefore, the heat resistance of the rubber tile is high, and even if a fired cigarette falls on the rubber tile, a burn mark is unlikely to remain. In addition, since a large number of cut surfaces of the heat conductive rubber particles appear on the surface of the surface layer portion, a mosaic-shaped clear surface pattern having an extremely decorative and excellent decorative property is automatically obtained.
