A method for producing a fiber-reinforced resin shaped product, by mold clamping and cold 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 comprising: disposing the molding material, which is heated and is in a plastic state, between the upper mold and the lower mold; initiating the mold clamping to apply a force in a substantially mold clamping direction to a certain site of the molding material; starting deformation of the molding material in the substantially mold clamping direction; applying a force in the substantially mold clamping direction to a fixing site which is present in 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 mold clamping to obtain a fiber-reinforced resin shaped product having an edge portion , wherein the molds have a cavity formed by the upper mold and the lower mold during the mold clamping, and have a pinching portion at which the cavity has a smaller thickness than a substantially central portion of the cavity, the pinching portion being formed at a substantially outer peripheral end portion of the cavity, and the molding material is disposed in the molds so that at least a part of the substantially outer peripheral end portion of the molding material in a plastic state is pinched by the pinching portion at the cavity during the mold clamping, thereby applying a force in the substantially mold clamping direction to the fixing site at the substantially outer peripheral end portion of the molding material, wherein in the mold clamping, a pinching constant Kp in units of MPa·cm 2 /kN defined by Expression p from a maximum pressure in units of MPa applied to the pinching portion, a pinching area in units of cm 2 , and a mold clamping force in units of kN is less than 0.5; Pinching portion maximum pressure MPa × pinching portion area cm 2 / 10 / mold clamping force kN = pinching constant Kp MPa ⋅ cm 2 / kN . disposing the molding material, which is heated and is in a plastic state, between the upper mold and the lower mold; initiating the mold clamping to apply a force in a substantially mold clamping direction to a certain site of the molding material; starting deformation of the molding material in the substantially mold clamping direction; applying a force in the substantially mold clamping direction to a fixing site which is present in 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 mold clamping to obtain a fiber-reinforced resin shaped product having an edge portion , wherein the molds have a cavity formed by the upper mold and the lower mold during the mold clamping, and have a pinching portion at which the cavity has a smaller thickness than a substantially central portion of the cavity, the pinching portion being formed at a substantially outer peripheral end portion of the cavity, and the molding material is disposed in the molds so that at least a part of the substantially outer peripheral end portion of the molding material in a plastic state is pinched by the pinching portion at the cavity during the mold clamping, thereby applying a force in the substantially mold clamping direction to the fixing site at the substantially outer peripheral end portion of the molding material, wherein in the mold clamping, a pinching constant Kp in units of MPa·cm 2 /kN defined by Expression p from a maximum pressure in units of MPa applied to the pinching portion, a pinching area in units of cm 2 , and a mold clamping force in units of kN is less than 0.5; Pinching portion maximum pressure MPa × pinching portion area cm 2 / 10 / mold clamping force kN = pinching constant Kp MPa ⋅ cm 2 / kN . <EOS>
