PROBLEM TO BE SOLVED: To repair a resin-unimpregnated part simply and surely and to conduct rational repair without causing the lowering of strength by a method in which the resin-unimpregnated part generated on a surface is covered with a bag base material, and an inside is evacuated, a resin is injected into the inside, and the resin-unimpregnated part is impregnated with the resin. SOLUTION: On the surface of a resin-unimpregnated part 2, for example, a resin diffusion medium 5 comprising a net-shaped body is arranged, and it is covered with a bag film 6 which is a bag base material from above it. A double bond tape 13, which is a seal member, is placed between the bag film 6 and an FRP structure 1 on the periphery of the part 2. A vacuum pump 7 is actuated in this state, an inside covered with the film 6 is evacuated through a suction pipe 8. A valve 11 is opened, a resin 9 in a resin tank 10 is injected from a resin supply pipe 12 into the part 2. After that, the film 6 and the medium 5 are removed, the injected resin is cured, and the resin-unimpregnated part 2 is repaired.
