Claim:
1. An energy-absorbing member having a structure in which a plurality of fiber reinforced resin layers are layered in a thickness direction of said member and including as said plurality of fiber reinforced resin layers, at least a plurality of unidirectional materials each comprising unidirectionally aligned reinforcing fibers and a resin and a plurality of cross materials each comprising a reinforcing fiber woven fabric and a resin, wherein lengths of said plurality of unidirectional materials in an external-loading direction are sequentially changed, a length of a unidirectional material located at a more inner-layer side in said thickness direction of said member is shorter than a length of a unidirectional material located at a more outer-layer side, and each of said unidirectional materials is layered at a condition between said cross materials.
