PROBLEM TO BE SOLVED: To provide a synthetic resin floor material which is excellent in all of productivity, strength, weatherability, and durability, and achieves high-quality design. SOLUTION: The floor material 1 is formed of a synthetic resin floor material main body 2, and a protective layer 3 for protecting at least a walking surface of the floor material main body 2. The floor material main body 2 is extrusion-molded of a synthetic resin-based material, and exhibits a transparent color or a translucent color having a high light transmissivity. The protective layer 3 is formed of a synthetic resin-based material having a weatherability higher than that of the synthetic resin-based material forming the floor material main body 2. The floor material main body 2 has a plurality of hollow portions 21 secured therein at regular intervals, which are partitioned by partition walls 22 having almost the same thickness s. Joint portions 23, 23 arranged on both lateral edges of the floor material main body are formed into a pair of fitting joints, and when both the floor materials 1 are adjacently jointed to each other, the total of thicknesses u of the respective joint portions 23, 23 fitted to each other are set to almost the same dimension as the thickness u of the partition wall 22.
