Energy-absorbing member

An energy-absorbing member configured to absorb impact energy when receiving an impact load, the energy-absorbing member comprising a fiber structure impregnated with a plastic, wherein

• the fiber structure includes a plurality of fiber layers that is laminated in a direction perpendicular to a direction in which a load is applied,
• each fiber layer includes an arrangement of a plurality of load direction yarns extending in the direction in which a load is applied,
• the fiber structure has interlayer bonding strength resulting from bonding of the plurality of fiber layers,
• the fiber structure includes
• a first end face, which is configured to first receive a load, and
• a second end face, which is opposite to the first end face in the direction in which a load is applied, the fiber structure includes
• a shape retention section including the first end face,
• a main section that includes the second end face and hinders propagation of breakage of the fiber structure, and
• a trigger section that is located between the shape retention section and the main section and serves as a starting point of breakage when receiving an impact load, and
• the shape retention section and the main section each have a woven structure that allows the shape retention section and the main section to have a higher interlayer bonding strength than the trigger section.
