To provide a crash energy absorbing part which is light in weight, and in which collapsing deformation into a bellows shape occurs more stably even when a crash load is applied in a direction crossing the shock-absorbing direction of the crash energy absorbing part. The crash energy absorbing part of the present invention is constructed of a member that is obtained by forming a sandwich metal sheet (1), which is formed by laminating a surface layer (3A, 3B) formed of a metal sheet on each side surface of a core layer (5) and bonding them. By controlling a deformation rate of a center layer of the sandwich metal sheet (1) for constructing the crash energy absorbing part, the crash energy absorbing part of the present invention is deformed at a short wavelength regardless of a direction of a crash load that is applied, whereby collapsing deformation into a bellows shape more stably occurs. |
