A fiber-reinforced composite material characterized by laminating a fabric made of flame-retardant fibers in more than one layer, laminating a fabric made of polyolefin fibers in the inner layer, and integrally molding it with resin, is lightweight, has high rigidity, and is impact resistant. Since it is possible to produce a fiber-reinforced composite material that is excellent in flame resistance and flame retardant, especially because of its concern about flame retardancy while paying attention to high performance such as light weight and impact resistance, a polyolefin fiber-reinforced composite material is used. This makes it possible to enter into vehicle applications that were difficult to achieve, and the effect is extremely large.
