To provide an impact absorption floor material which has excellent load resistance while having an absorption effect by a soft layer.SOLUTION: An impact absorption floor material 1 comprises: a topfloor material 11; an underfloor material 12 provided below the topfloor material and formed of a soft material; and an intermediate material 13 provided between the topfloor material and the underfloor material. The underfloor material 12 has an Asker C hardness of 20 or more to 60 or less and a thickness of 4 or more to 15 mm or less. The intermediate material 13 has a thickness of 2 or more to 8 mm or less, has a strain (ε(σmax)) in which bending strength reaches the maximum in a three point bending test according to JIS K7074 of 0.5% or more, and has a bending elastic modulus of 1 to more to 15 Gpa or less.SELECTED DRAWING: Figure 1
【課題】軟質層による吸収効果をもちながらも、耐荷重性に優れた衝撃吸収床材を提供する。【解決手段】衝撃吸収床材１は、床上材１１と、床上材の下方に設けられ、軟質材料で形成された床下地材１２と、床上材と床下地材との間に設けられた中間材１３と、を備え、床下地材１２は、アスカーＣ硬度が２０以上６０以下、かつ厚みが４ｍｍ以上１５ｍｍ以下であり、中間材１３は、厚みが２ｍｍ以上８ｍｍ以下、ＪＩＳ Ｋ７０７４による３点曲げ試験において曲げ強度が最大になる歪み（ε（σｍａｘ）)が０．５％以上、かつ曲げ弾性率が１ＧＰa以上１５ＧＰa以下となっている。【選択図】図１
