<p>PROBLEM TO BE SOLVED: To provide an impact absorption sheet having high impact absorption performance and its production method.SOLUTION: An impact absorption sheet 10 has a resin layer 1 and cells 2 present in the resin layer 1, and the cells 2 have a ratio of the average pore diameter Dz in the thickness direction to the average pore diameter Dxy in the in-plane direction of the resin layer 1, or an aspect ratio Dz/Dxy, is 2.4 or higher. The impact absorption sheet 10 has a storage elastic modulus at 20-30°C of 1×10to 5×10Pa. The resin layer 1 is composed of an ionizing radiation curable resin, and non-foam layers 3A and 3B free of cells 2 may be provided on both sides in the thickness direction of the resin layer 1.</p> |
