Abstract: The present invention provides a metal foam production method that enables a foaming process to be performed at low cost and enables controlling of the shape of metal foam. According to the present invention, a mold that transmits light and a precursor prepared by mixing a metal with a foaming agent are used, and a metal foam is produced by irradiating the precursor with a light transmitted through the mold to thereby heat and foam the precursor so as to obtain a metal foam, while controlling the shape of the metal foam by the mold.
