PROBLEM TO BE SOLVED: To provide a method of manufacturing a fiber-reinforced resin structure capable of forming a fiber-reinforced resin layer around a core material in a void-free state and following even a complicated final shape. SOLUTION: The method has the process of laying a core material 12 around an expandable hollow material 11, the process of laminating a prepreg 15 having an unhardened resin 15a and a reinforcing fiber 15b around the core material to cover the core material 15, the process of laying the core material 12 laminated and covered with the prepreg 15 in a cavity 4 of a mold 1 and causing the hollow material 11 to expand within the cavity 4 of the mold 1 so as to pressurize the unhardened resin 15a and the reinforcing fiber 15b between the mold 1 and the core material 11 and the process of heating the pressurized unhardened resin and reinforcing fiber to harden the resin 15a so as to form a fiber-reinforced resin layer 16 around the core material 12.
