To provide an impact-absorbing resin laminate that can absorb impact on its surface to prevent an injury, and also has high shape reproducibility and a method for producing the same.SOLUTION: An impact-absorbing resin laminate has a resin-made front surface layer 1, a resin-made back surface layer 2 that is less susceptible to deformation than the front surface layer 1, and an elastic material-made intermediate layer 3 disposed between the front surface layer 1 and the back surface layer 2. The surface layer 1 is at least partially composed of a resin that can be molded without pressure. The entire resin laminate is at least partially three-dimensionally molded.SELECTED DRAWING: Figure 1 【課題】表面に対する衝撃を吸収して怪我を防止することができるうえ、形状の再現性の高い衝撃吸収性の樹脂積層体及びその製造方法を提供すること。【解決手段】樹脂製の表面層１と、表面層１よりも変形しにくい樹脂製の裏面層２と、表面層１と裏面層２との間に配置される弾性素材製の中間層３とからなり、表面層１の少なくとも一部には無圧成形可能な樹脂が用いられ、樹脂積層体全体の少なくとも一部を立体的に成形する手段を採用した。【選択図】 図１
