    摘要： A method for producing a fiber-reinforced resin shaped product, by clamping and press-molding a molding material containing reinforcing fibers and a thermoplastic resin as a matrix in molds having an upper mold and a lower mold. The method includes: disposing the molding material heated in a plastic state, between the upper mold and the lower mold; initiating the clamping to apply a force in a substantially clamping direction to a certain site of the molding material: starting deformation of the molding material in the substantially clamping direction; applying a force in the substantially clamping direction to a fixing site which is at least a part of a substantially outer peripheral end portion of the molding material but is different from the certain site; pressing and fixing the fixing site, and completing the clamping to obtain a fiber-reinforced resin shaped product having an edge portion.
