To provide an impact absorbing member that can be arranged flexibly in accordance with the shape of the space where the impact absorbing member is to be arranged. An impact absorbing member according to an exemplary aspect has a plurality of structural members each having hollow tetrahedron structures arranged continuously at prescribed intervals on an axis. Further, an impact absorbing member according to another exemplary aspect has a plurality of structural members woven by a connecting member that is disposed in a direction orthogonal to an axial direction of the structural members.
