A high-strength and high-rigidity fiber-containing aliphatic polyester resin composition that prevents cellulose fibers from being shortened and suppresses aggregation of cellulose fibers in a biodegradable resin. The purpose is to obtain. At least one aliphatic polyester resin (A) selected from an aliphatic polyester obtained by reacting an aliphatic diol with an aliphatic dicarboxylic acid and / or a derivative thereof, and a poly (oxycarboxylic acid). 1) to 99 parts by weight, 1 to 20 parts by weight of a polymer dispersant (B) having a weight average molecular weight of 1,000 to 100,000, and 98 to 1 part by weight of cellulosic fiber (C). A group polyester resin composition is used. [Selection figure] None |
