Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition which can shorten the molding time and hardly causes deformation in a molded article even when the temperature of a mold is low and from which a molded article excellent in releasability from a mold and having high heat resistance can be obtained, and to provide a molded article obtained by molding the same. SOLUTION: (1) The polylactic acid resin composition includes a crystal nucleus agent and a glycerin alkyl ether or polyglycerin alkyl ether. (2) The polylactic acid resin composition especially includes 0.1-10 mass% crystal nucleus agent and 0.1-10 mass% glycerin alkyl ether or polyglycerin alkyl ether. COPYRIGHT: (C)2010,JPO&INPIT
