PROBLEM TO BE SOLVED: To provide a method for producing a foamed molding which is light in weight and high in rigidity. SOLUTION: In the method, at least two reaction solutions are supplied into a mold, polymerized, and cured in the mold. The gas concentration of the reaction solutions to be supplied into the mold is made below 0.02 wt.% at the start of the supply and changed to be 0.02-1 wt.% after the start of the supply to complete the supply.
