To obtain effective reinforcing effect by impregnating reinforcing fiber with a matrix resin in and sticking a fiber reinforced resin plate to be cured on a prescribed surface of a structure with a resin.
A reinforcing fiber mainly comprising a carbon fiber is impregnated with a matrix resin such as an acrylic resin to be cured, and a reinforcing material of a structure comprising a fiber reinforced resin plate is obtained. In this case, the softening temperature of the cured matter of the resin is 40-100°C, preferably 40-70°C as the matrix resin. The blending amount of the reinforced fiber in the fiber reinforced resin plate is in the range of 200-1200 g/m2. The reinforcing material is stuck on the prescribed surface of a structure with a resin. The meandering of the reinforced fiber accompanying sticking working does not occur, the resin is not reguired to be impregnated before sticking or at the time of sticking, and effective reinforcing effect can be obtained.
