Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a foamed molded product having biodegradability and high resistance against uniform external force, and against non-uniform external force as well. SOLUTION: This foamed molded product is provided by using a polyester-based resin having the biodegradability, wherein the foamed product has a permanent compression set percentage of ≤30% and a displacement of a flexure stress decreasing point of ≥1.0 cm. An aliphatic polyester is preferably used as the polyester-based resin, and polylactic acid-based resin is especially preferably used as the polyester-based resin. COPYRIGHT: (C)2005,JPO&NCIPI
