There is provided a method for repairing a member comprising a fiber-reinforced plastic, which method can repair a through hole easily at a low cost. When a through hole 20 is repaired, a temporary hole 11 is formed, a fabric sheet 30 comprising reinforcing fibers is rolled into a cylindrical shape and inserted into the temporary hole 11, the fabric sheet 30 is impregnated with a resin, the resin is cured, and a new through hole 20′ is formed.
