PROBLEM TO BE SOLVED: To easily provide a floor material prevented from being pushed up by thermal deformation in forming the floor material using a woody resin foam molding of excellent woody feeling and recycling fitness as a base material. SOLUTION: The floor material is formed of the woody resin foam molding 1 formed by foaming a woody resin composition comprising thermoplastic resin and a wooden filler. The back face of the woody resin foam molding 1 has groove parts 2 in lattice shape, and the groove parts have a depth of 0.1-0.5 times to the thickness of the floor material. With the groove parts of lattice shape, stress in width and length directions caused by thermal expansion can be relieved to hardly cause push-up even if a construction area is large.
