To provide an impact absorption member capable of constituting an impact absorption member having a successive breaking function and capable of preventing corrosion (electric corrosion) of a fastening fixing part into a bumper reinforcement or a vehicle body.SOLUTION: An impact absorption member 10 to be arranged between a bumper reinforcement and a vehicle body is provided. The impact absorption member 10 includes a tip part 20 to be fastened to the bumper reinforcement, a base end flange part 30 to be fastened to the vehicle body, and an absorption member body part 40 for connecting the tip part 20 and the base end flange part 30 by extending in a longitudinal direction of the vehicle body. The absorption member body part 40 is formed with a carbon fiber reinforced plastic layer 40C. Fastening fixing parts A', D' of the tip part 20 and the base end flange part 30 are formed of glass fiber reinforced plastic layers 20G, 30G.SELECTED DRAWING: Figure 1
