PROBLEM TO BE SOLVED: To provide a manufacturing method of a foamed molded product characterized in that the part in the vicinity of the vent hole of the molded product does not become too hard without discharging a raw material from the vent hole. SOLUTION: The foamed molded product is manufactured by supplying a foamable resin raw material 16 into a mold 1 provided with the vent hole 8 to foam and cure the same. This manufacturing method of the foamed molded product comprises a process for arranging a panel-shaped slab 9, to which an air impermeable sheet 11 capable of covering the opening part 15 of the vent hole 8 is bonded, in the mold 1 and opposing the air impermeable sheet 11 to the vent hole 8 so as to provide an interval, a process for supplying the foamable resin raw material 16 into the mold 1 to foam and cure the same, and a process for pressing the panel-shaped slab 9 to the vent hole 8 by the foaming pressure of the foamable resin raw material 16 to close the opening part 15 of the vent hole 8 by the air impermeable sheet 11.
