PROBLEM TO BE SOLVED: To provide a polylactic acid-based film which is excellent in biodegradability, coverability, printability and heat resistance and is suitable for packaging materials. SOLUTION: The polylactic acid-based oriented film comprises a polylactic acid-based composition containing poly-L-lactic acid, poly-D-lactic acid, and a filler, wherein the peak ratio (peak 1/peak 2) of the peak height (peak 1) of the maximum endothermic peak in endothermic peaks in a range of 150 to 200°C to the peak height (peak 2) of the maximum endothermic peak in endothermic peaks in a range of 205 to 240°C in a DSC measurement is≤0.2.
