PROBLEM TO BE SOLVED: To provide a floorboard in which a woody resin foamed molding excellent in a woody touch and recyclability is used as a base material, and which has excellent physical properties well balanced in terms of heat insulating properties, a sense of walking, damage resistance, indentation resistance and the like. SOLUTION: This floorboard is characterized as follows: a decorative sheet 2, which is predominantly composed of a thermoplastic resin akin to a thermoplastic resin 13, is laminated on a surface of the woody resin foamed molding 1 which contains the thermoplastic resin 13 and a wood-based filler 14 and is foamed (provided with foam 15); the molding 1 is composed of a surface layer part 12 which has an expansion ratio of 1.0-1.1 times and a thickness of 0.1-2 mm, and a core part 11 which has an expansion ratio of 1.2-3.0 times; and the thermoplastic resin 13 is a polyolefine-based resin in which an initial flexural modulus of elasticity is in a range of 700-3,000 MPa.
