PROBLEM TO BE SOLVED: To provide an aliphatic polyester resin composition having greatly more excellent hydrolysis resistance than that of a conventional aliphatic polyester resin composition, and a method for producing the same.SOLUTION: There is provided an aliphatic polyester resin composition formed of an aliphatic polyester resin (A), a monocarbodiimide compound (B), and a polycarbodiimide compound (C). With respect to the total of (A) to (C), (A)+(B) is 90-99.9 mass%, (C) is 0.1-10 mass% and 1.0-7.78 times the amount of (B), and the used amount of (B) is such an amount that a carboxy group concentration of (A) is 5 mol/10kg or less. |
