PROBLEM TO BE SOLVED: To easily reinforce a construction by sticking prepreg formed by impregnating photo-curing resin in light transmissive reinforced fiber, in a plurality of layers to the wall surface or the like of the construction, and curing resin of the prepreg by light irradiation or sunlight. SOLUTION: Photo-curing resin such as unsaturated polyester resin, phenol resin, acrylic resin, polyamide resin, epoxy resin or epoxy acrylate resin is impregnated in light transmissive reinforced fiber such as glass fiber, aramid fiber, acrylic fiber, transparent polyester fiber, polyethylene fiber or nylon fiber to form prepreg 1. At the time of work execution, the prepreg 1 is stuck in two or more layers to the wall surface 2 of a construction or wound around a reinforced concrete column 3, and resin of the prepreg 1 is cured by light irradiation or sunlight. Or an L-member may be disposed at the corner part of the wall surface 2 or the corner part of the column 3 of the construction to stick or wind the prepreg 1 thereon. The construction can therefore be easily reinforced.
