Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a fiber-reinforced resin sheet for reinforcement or repair, which enables observation with time of the surface of a concrete structure and is free from leakage of an uncured adhesive during construction, and to provide the fiber-reinforced resin sheet.SOLUTION: The method for production of the fiber-reinforced resin sheet includes: (1) a liquid layer-forming step of applying a transparent curing resin composition (A) for a body onto a carrier film or a barrier layer formed on the carrier film; (2) a pre-impregnation step of making a mesh body drive while immersing it in an impregnation tank in which a transparent curing resin composition (B) for pre-impregnation having compatibility with the transparent curing resin composition (A) and having a viscosity of 50-15,000 cP is injected, and then permitting the passage of the mesh body retaining a resin liquid between the impregnation rollers to impregnate and defoam it at a roller linear pressure of 5-30 N/cm; (3) a main impregnation step of feeding the mesh body impregnated with the resin composition (B) in the liquid layer of the resin composition (A) from the upper surface thereof, and further placing a first cover film on the upper face thereof to impregnate the mesh body on the carrier film or by being sandwiched between the carrier film and the barrier layer formed on the carrier film with the resin composition (A); and (4) a curing step of curing the resin compositions (B) and (A).
