The present invention provides a flame retardant fiber which has good handling property of a resin at the time of molding, has excellent flame retardancy after molding, and does not generate a halogen-containing gas even when burned, and is lightweight and has high rigidity. To provide a reinforced composite material. A flame-retardant fiber-reinforced composite material of the present invention, vinyl ester resin, for at least one 100 parts by weight is selected from the group consisting of unsaturated polyester resin and silicone resin, 50% particle size D 50 It is obtained by impregnating and curing a fiber base material with a matrix resin added with 10 to 17 parts by mass of an organic phosphate metal salt particle having a particle size D 95 of 10 μm or less and a 95% particle diameter D 95 of 30 μm or less. .
