Zusammenfassung:	PROBLEM TO BE SOLVED: To develop a polylactic acid-based oriented film having biodegradability and excellent in transparency and heat resistance.SOLUTION: This polylactic acid-based oriented film comprises a polylactic acid-based composition containing poly-L-lactic acid and poly-D-lactic acid, and the peak ratio (peak 1/peak 2) of peak height (peak 1) of maximum endothermic peak among endothermic peaks in the range of 150-200°C to the peak height (peak 2) of maximum endothermic peak among endothermic peaks in the range of 205-240°C is 0.2 or less.
