PROBLEM TO BE SOLVED: To obtain an aliphatic polyester composition having biodegradability and excellent in flexural modulus, tensile strength and impact strength, and useful for various applications such as an injection-molded article. SOLUTION: This aliphatic polyester composition comprises a polylactic acid (A) and an aliphatic polyester polyether copolymer (B), wherein a content of the aliphatic polyester polyether copolymer (B) is≥1 pt.wt. to≤60 pts.wt. based on 100 pts.wt. of the total amount of the poly lactic acid (A) and the aliphatic polyester polyether copolymer (B).
