There is provided a process for producing a fiber-reinforced resin material capable of mitigating damage to and defects in reinforcement fibers and of performing lamination with the reinforcement fibers positioned with ease, while at the same time causing them to conform to the shape of the mold with ease at the time of molding. It comprises at least: a step of producing a fiber-reinforced resin sheet (4A) from a reinforcement fiber sheet (2) and a resin sheet (3A) comprising a thermoplastic resin; a step of molding the fiber-reinforced resin sheet (4A) in such a manner as to form a protruding part (4c) on one face (4a) of the fiber-reinforced resin sheet (4A) along one direction and to form a recessed part (4d) along the one direction in another face (4b); a step of laminating the fiber-reinforced resin sheet (5A) while causing at least the protruding part (4c) of the molded fiber-reinforced resin sheet (5A) to engage with a fiber-reinforced resin sheet (5A) that is to be laminated therewith; and a step of molding the laminated fiber-reinforced resin sheets (5A) into the fiber-reinforced resin material while pressurizing and heating them so as to impregnate the reinforcement fibers with the thermoplastic resin.
