Provided is a method of producing a fiber-reinforced composite material, involving impregnating a fiber structure with a resin by using the pressure difference between a vacuum pressure and an atmospheric pressure and thereafter curing the resin, the method comprising: impregnating a mixture of a bromine-containing resin 22 and a powdered flame retardant 21 that contains at least one component selected from aluminum hydroxide and magnesium hydroxide and has an average particle size in the range of 0.1 to 20 μm into a fiber structure 10 that has a mode value for the size of fiber surrounded individual openings in the range of 0.03 to 3 mm2 and an opening area percentage in the range of 0.1 to 10%, from a surface direction of the fiber structure 10, to unevenly distribute the powdered flame retardant 21 in a surface layer of the fiber structure 10. The present invention can simply and conveniently produce a highly flame-retardant and lightweight fiber-reinforced composite material that exhibits a high strength.
