Summary:PROBLEM TO BE SOLVED: To provide a method for repairing a member made of a fiber-reinforced resin which can surely and efficiently repair even a part required for the smoothness of a matrix. SOLUTION: A plug 20 formed in advance is inserted into a recess 11 formed in a part to be repaired in the member 10, and a resin is injected, used for impregnation, and cured by heat treatment to carry out repairing. In a vacuum bag 31 used for injecting and impregnating the resin, an annular pass-media is provided in a region facing the outer peripheral part of the recess 11, and the injected resin can be made to flow preferentially along the pass-media. In this way, the resin flows annularly in the peripheral part of the recess 11, falls into the recess 11 by gravity, and can be packed/impregnated uniformly into the recess 11.
