A method for molding a fiber-reinforced plastic comprising: forming a core (4) having a desired shape by accommodating a grain group (4a) containing a plurality of grains in a flexible bag (4b); disposing a prepreg (3) containing a resin and fiber in a periphery of the core (4); disposing the core (4) and the prepreg (3) disposed in the periphery of the core (4) between an upper mold (2) and a lower mold (1) of a molding die (15); and performing compression molding by closing the molding die (15), wherein the method includes: holding the upper mold (2) and the lower mold (1) by mold interval holding means so as not to cause an interval therebetween to be increased; pressing a portion of one of outer surfaces of the core to increase internal pressure of the core (4) and deform the core (4) by pressing means (5, 5a) which comes into the cavity between the upper mold (2) and the lower mold (1); and increasing cohesion between the prepreg (3), the mold, and the core (4) by the pressing and the deformation of the core (4).
