PROBLEM TO BE SOLVED: To avoid local strength reduction of a foamed resin molding. SOLUTION: A method for molding the foamed resin molding includes a process of injecting and supplying a molten foamable resin 70 into a cavity 27 partitioned and formed in a molding die 4, a process of foaming the molten foamable resin 70 in the cavity 27 by moving the molding die 4 in a die opening direction and a process of molding the foamed resin molding by curing the molten foamable resin 70 after finish of moving the molding die 4. In the foaming process, the molten foamable resin 70 at a weld producing part (a part corresponding to a weld part of the foamed resin molding) 23 is pressurized once and then the molding die 4 is moved in the die opening direction and foaming of the molten foamable resin 70 is started.
