PROBLEM TO BE SOLVED: To provide a molded article composed of a polylactic acid-based polymer and having excellent transparency and heat resistance, in which evaporation, oozing-out and extraction (bleedout) of lactide, etc., are suppressed when used as a molded article and further, odor emitted when used under heating is suppressed. SOLUTION: The molded article is composed of a polylactic acid resin composition obtained by formulating (A) a polylactic acid resin having≥50,000 weight-average molecular weight with (B) a poly(meth)acrylate and/or a polyvinyl compound having≥60°C glass transition temperature. In the molded article, melting calorie (ΔHm) of crystal of the molded article in DSC temperature-raising measurement is≤10 J/g and lactide content in the molded article is≤2 mass%.
