PROBLEM TO BE SOLVED: To provide a molding method which, relating to a method of obtaining a styrenic resin foamed molding by impregnating styrenic resin particles with an easily-volatile foaming agent and a surfactant, filling the pre-expanded particles obtained by heating into a mold and subjecting to heating and cooling processes, eliminates portion-to-portion fluctuations of the antistatic properties of the obtained foamed molding. SOLUTION: In carrying out in-mold foam molding by impregnating styrenic resin particles with an easily-volatile foaming agent and a nonionic surfactant, filling the pre-expanded particles obtained by heating into a mold and subjecting to heating processes, the time of the water cooling process after the in-mold foaming, relative to the total time of the heating processes, is prolonged compared with the conventional one.
