A preform can be molded by resin transfer molding and yields a composite material having excellent strength and excellent interlaminar debonding resistance. The preform, which is for producing a fiber-reinforced composite, comprises layers of laminated structure of a reinforcing material comprising reinforcement fibers and has, between these layers, a layer comprising a thermoplastic resin and having space so as not to inhibit a liquid resin from flowing therethrough. The preform is molded to yield a fiber-reinforced composite material.
