PROBLEM TO BE SOLVED: To provide a simple method for producing a low-volatile content polylactic acid foamed molding excellent in dimensional stability under high-temperature high-humidity conditions and to provide a molding produced thereby. SOLUTION: A low-volatile content polylactic acid foamed molding is produced by subjecting a polylactic acid foamed molding containing a hydrocarbon blowing agent to treatment with carbon dioxide.
