Zusammenfassung:	To suppress detection failures of cracks in a structure where cracks in the structure are detected by light emission due to light irradiation by breaking a shielding layer.SOLUTION: A reinforcing member is used by bonding to a surface of a structure, and comprises a fiber sheet containing fibers that emit light when irradiated with light, and a shielding layer that blocks the light applied to the fiber sheet. When a tensile test is performed on the reinforcing member, the shielding layer breaks before the fiber sheet, and the fiber sheet is exposed from the broken portion.SELECTED DRAWING: Figure 3 【課題】遮蔽層を破断させて光の照射による発光により構造物の亀裂を検出する構造において、構造物の亀裂の検出不良を抑制する。【解決手段】補強部材は、構造物の表面への接着により使用される補強部材であって、光の照射により発光する繊維を含む繊維シートと、前記繊維シートへ照射される光を遮蔽する遮蔽層と、を備え、前記補強部材に対し引張試験を行った場合に、前記繊維シートよりも先に前記遮蔽層が破断して当該破断部分から前記繊維シートが露出する。【選択図】図３
