To easily manufacture a foamed body even when a large complicated mold is used.

Molten metal is prepared by melting a metal or an alloy. Then a thickner is added to and mixed with the molten metal, further a foaming agent is added to and mixed with the molten metal, and the molten metal is stirred to thereby obtain a foaming-incomplete molten metal, which is unfoamed or has a foaming rate of ≤4 times. The foaming-incomplete molten metal is poured from the upper opening of a riser, which is connected to a three-dimensional complicated shape mold, then the upper opening of the rising is sealed, and the molten metal is allowed to flow into the three-dimensional complicated shape mold to fill the mold and foamed to mold the molten metal into a three-dimensional complicated shape.
