PROBLEM TO BE SOLVED: To provide a method of manufacturing a fiber-reinforced resin structure by which a resin passage enabling a large amount of resin to flow so as to further enhance impregnation efficiency, can be simply formed, and a manufacturing device using this method. SOLUTION: This method is a method of manufacturing the fiber-reinforced resin structure by vacuum-packing a fibrous base material laminated in a cavity 3 and injecting a fluid resin into the vacuum pack. The outside of a first vacuum-packing sheet 1 for forming the cavity 3 is covered with a second vacuum-packing sheet 8. Next, the fibrous base material 7 is vacuum-packed in the way that a resin passage molded component 11 with an irregular part is superposed over the fibrous base material 7 toward the sheet 1, between the sheet 1 and the sheet 8. Thus a vacuum bag is structured in a double layer fashion. After that, the resin passage is formed inside the cavity 3 by adjusting the pressure of the vacuum bag parts A and B, then the fluid resin is injected into between the sheets 1 and 8 and finally the fibrous base material 7 is impregnated with the fluid resin to obtain the fiber-reinforced resin structure.
