An impact absorbing structure is provided with: a first member formed from a metal material; and a second member extending in the axial direction of the first member, the first member having a cylindrical shape, and the length of the second member in the axial direction being 15-75% of the length of the first member in the axial direction. When the end-to-end distance between the end of the first member and the end of the second member is D, the maximum radius of curvature of the first member is R, and the plate thickness of the first member is t, Dlt is satisfied. 0.40 Rt, the impact absorbing structure having a bonding line between the first member and the second member extending in a direction different from the circumferential direction of the first member.
