The repairing material 1 has a pipe inner peripheral face 2 abutted on the inner peripheral wall 12 of the pipe opening 11, a flange face 3 abutted on the vertical wall face 13 around the pipe opening, a pipe outer groove face 4 abutted on an outer groove 14 of the pipe opening, and sleeve faces 6, 6 abutted on both sleeves 15, 15 of the pipe opening. The repairing material 1 is formed into a development shape. The development-shaped repairing material 1 is composed of an FRP material including a photocurable resin.
