An energy-absorbing member includes a fiber structure. The fiber structure includes a first end face configured to first receive a load and a second end face opposite to the first end face in the direction that the 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. 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.
