To provide an impact absorbing body which can suppress a bellows deformation.SOLUTION: In an impact absorbing body which is constituted of a hollow blow molding, the blow molding comprises a front face, a rear face opposing the front face, and an intermediate face for connecting the front face and the rear face. The intermediate face comprises a pair of opposing side faces, and a pair of connecting faces for connecting the pair of side faces, the blow molding comprises an annular parting line which passes the front face, the rear face and the pair of connecting faces, the side faces comprise lateral groove ribs and protrusive bent parts, the protrusive bent parts are regions which are protrusively bent toward the outside of the blow molding, the protrusive bent parts comprise in-groove regions and out-groove regions, the in-groove regions are regions in which the lateral groove ribs are locally shallowed, the out-groove regions are regions extending to the lateral groove ribs in a non-parallel manner at the outside of the lateral groove ribs, and one-side ends of the out-groove regions adjoin the in-groove regions.SELECTED DRAWING: Figure 1
