Summary:To suppress performance deterioration of an energy absorbing body.SOLUTION: An energy absorbing body 10 is formed of a plate-like fiber structure 11 comprising a plurality of weft layers having weft 13 and a plurality of warp layers having warp 14 crossing the weft 13 in a stacked manner. The fiber structure 11 includes a first flat portion 16 and a second flat portion 17 made by binding the weft layers and the warp layers using binding strings in a laminate direction, which is a direction of lamination of the weft layers and the warp layers. The fiber structure 11 includes a second curve surface 20 having an overlap portion where end portions 11a and 11b of the fiber structure 11 are connected by overlapping in the laminate direction.SELECTED DRAWING: Figure 1 【課題】エネルギー吸収体の性能低下を抑制すること。【解決手段】エネルギー吸収体１０は、緯糸１３を有する複数の緯糸層と、緯糸１３に交差した経糸１４を有する複数の経糸層と、が積み重ねられた板状の繊維構造体１１からなる。繊維構造体１１は、緯糸層と経糸層が積み重ねられた方向を積層方向とすると、緯糸層及び経糸層が拘束糸によって積層方向に拘束されてなる第１平面部１６及び第２平面部１７を備える。繊維構造体１１は、繊維構造体１１の端部１１ａ，１１ｂ同士が積層方向で重なって接続された重なり部を有する第２曲面部２０を備える。【選択図】図１
