To provide a shock absorber which is excellent in shock-absorbing performance and also in durability, and can be used in various applications.SOLUTION: A shock absorber 1A includes a three-dimensional structure comprising a unit structure U repeatedly, regularly and continuously arranged in at least one direction, the unit structure U being in a three-dimensional shape formed by a wall 10 having an external shape defined by a pair of parallel curved surfaces. The three-dimensional structure is composed of a triply periodic minimal surface with a thickness added thereto, and has a meandering portion which is a portion presenting a cross-sectional shape extending in a meandering manner when the three-dimensional structure is cut along at least a specific plane. The shock absorber 1A comprises a reinforcement portion 20 to reinforce a turning point of the meandering portion.SELECTED DRAWING: Figure 1 【課題】各種の用途に使用することが可能な、緩衝性能に優れるとともに耐久性にも優れた緩衝材を提供する。【解決手段】緩衝材１Ａは、並行する一対の曲面によって外形が規定される壁１０にて形作られた立体的形状を単位構造体Ｕとし、当該単位構造体Ｕが少なくとも一方向において規則的にかつ連続的に繰り返し配列されてなる立体構造物を含むものであり、当該立体構造物は、三重周期極小曲面を基準にこれに厚みを付けたものからなり、少なくとも特定の平面に沿って切断した場合に蛇行状に延在する断面形状が現れる部位である蛇行部を有する。緩衝材１Ａは、当該蛇行部の方向転換点を補強する補強部２０を備える。【選択図】図１
