PROBLEM TO BE SOLVED: To provide a floor material having an excellent impact relieving property, sitting comfort and stepping comfort, while having thinness and light-weight.SOLUTION: In an impact relieving floor material, a floor material comprises a buffer layer arranged in the lowest layer, a plate material adjacently arranged on the upper side of the buffer layer, and a buffer layer arranged on the uppermost layer on the opposite side to the buffer layer via the plate material. The buffer layer arranged on the uppermost layer has a compressive elastic modulus within a range of 100-2500 kPa and a thickness within a range of 0.5-4 mm, the buffer layer arranged on the lowest layer has a compressive elastic modulus within a range of 10-500kPa, and the plate material has a product of a flexural elastic modulus and a thickness of 1.0×10or more.SELECTED DRAWING: Figure 1 |
