PROBLEM TO BE SOLVED: To provide a method for producing a fiber-reinforced resin composite material 10, even in the case a resin comprising a reinforcing fiber on the surface of a core material 13 is injection-molded to produce a fiber-reinforced resin composite material, capable of increasing the strength of the fiber-reinforced resin composite material 10.SOLUTION: There is provided a method for producing a fiber-reinforced resin composite material at least including: a core material 13 made of a first fiber-reinforced resin comprising a first reinforcing fiber; and a covering layer 14 made of a second fiber reinforced resin covered on the surface of the core material 13 and having a fiber length longer than that of the first reinforcing fiber. In the surface of the core material 13 covered with the covering layer 14, a plurality of recessed parts 17 are formed, and when the core material 13 is covered with the covering layer 14, gaps of 2 mm or lower are formed on the surface other than the recessed parts of the core material 13, and the covering layer 14 is molded by injection-molding the second fiber reinforcing resin on the gaps. |
