PROBLEM TO BE SOLVED: To provide a floor material that gives stable walking feeling, has scratch resistance on a surface and also has sufficient shock absorbing properties.SOLUTION: The floor material to be used by being laid on a surface of a floor face has at least a hard layer provided at a surface side thereof and a soft layer provided at a floor face side thereof. The hard layer has a bending elastic modulus of 1,000-6,000 MPa measured in conformity to JIS K 7171, and the soft layer has a compressive elasticity modulus of 0.01-0.06 MPa measured in conformity to JIS K 7220. The hard layer is a medium density fiberboard with a thickness of 3-9 mm, and the soft layer is made of a polyolefin resin sheet having a thickness of 3-9 mm and an expansion ratio of 5-12 times. |
