PROBLEM TO BE SOLVED: To provide a floor material which is produced by forming and hardening a surface material on an upper surface of a base board, and stably and robustly maintains connection between the base board and the surface material over a long period of time. SOLUTION: The floor material has the surface material 2 which is formed and hardened on the upper surface of the base board 1, and a number of anchors 3 protruding from the upper surface of the base board 1 in one body with the same, are embedded in the surface material 2 before hardening, to thereby connect the surface material 2 and the base board 1 to each other. A number of support legs 6 protruding from a lower surface of the base board 1 in one body with the same function to support the floor material on underfloor ground surface via multiple points. The floor material has base board connection holes 4 formed therein at immediately lower locations of the respective anchors 3 in a manner penetrating the base board 1, and therefore the surface material 2 before hardening is poured into the base board connection holes 4 so as to be compatible with the anchors 3, which contributes to good connection between the surface material 2 and the base board 1.
