PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition that has a large folding strength, excellent transparency and also flexibility and provide molded products therefrom. SOLUTION: The polylactic acid resin composition includes 5 to 50 pts.wt. of a plasticizer based on 100 pts.wt. of a lactic acid polyester having the lactic acid unit (I) and the polyester unit (II) at a weight ratio of 10:90 to 90:10, and has a glass transition point of less 60°C. In another embodiment, the polylactic resin composition includes 5 to 50 pts.wt. per 100 pts.wt. of the macromolecular component comprises this lactic acid polyester and a lactic acid homopolymer.
