PROBLEM TO BE SOLVED: To provide a biodegradable resin composition by which processability and moldability of a polyester resin having biodegradability are considerably improved, and which contains highly safe compounds giving little load on the environment. SOLUTION: The biodegradable polyester resin composition contains a processability-improving agent. The processability-improving agent is a hydrocarbon wax having a carboxy group in the molecule,≥10 acid value and≤5,000 average molecular weight. The content of the hydrocarbon wax is 0.01-5 pts. by mass based on 100 pts. by mass of the biodegradable polyester resin. COPYRIGHT: (C)2005,JPO&NCIPI
