PROBLEM TO BE SOLVED: To provide a transparent fiber-reinforced resin sheet for reinforcement or repair, which enables observation with time of a surface of a concrete structure and is free from leakage of an uncured adhesive during the construction. SOLUTION: The fiber-reinforced resin sheet 100 for repairing or reinforcing the concrete structure includes: at least an air-impermeable layer 101 made of a transparent resin; and a fiber-reinforced resin body layer 102 obtained by impregnating and curing a mesh body, in which predetermined openings are formed by the reinforced fiber, with a transparent hardening resin 20 having compatibility with the air-impermeable layer.
