PROBLEM TO BE SOLVED: To obtain a polylactic acid-based resin composition having a quick crystallization rate, large folding endurance and excellent trasparency, and also to provide a molded article of the composition having excellent heat resistance. SOLUTION: The polylactic acid-based resin composition comprises 100 pts. wt. of a polymer component consisting of a lactic polyester having a lactic component (I) and a polyester component (II) in the weight ratio of 10:90-90:10 and polyactic acid and 0.1-5 pts. wt. of at least one kind of a transparent nucleating agent selected from the group of compounds consisting of aliphatic carboxylic acid amides, aliphatic carboxylic acid salts, aliphatic alcohols and aliphatic carboxylic acid esters. The molded article prepared from the composition has a specific transparency and heat characteristics. COPYRIGHT: (C)2004,JPO
