The present application provides a technique, in an impact absorbing member comprising a tube wall and a flange member, for reducing variation in the relationship between a compressive load on the impact absorbing member and the degree of compressive deformation. An impact absorbing member 10 comprises a first main body 17 and a second main body 60. The first main body 17 comprises a first partial tube wall 19 and first flange members 20, 21. The second main body 60 comprises a second partial tube wall 62 and second flange members 64, 66. The first flange member 20 and the second flange member 66 are joined intermittently in an axial direction of the tube. The first flange member 21 and the second flange member 64 are joined intermittently in the axial direction of the tube. A space is formed, in a part of a section where the first flange members 20, 21 and the second flange members 64, 66 are not joined in the axial direction of the tube, between a first partial tube wall 19 side end part of the first flange members 20, 21 and a second partial tube wall 62 side end part of the second flange members 64, 66.
