Abstract: PURPOSE: A biodegradable resin composition is provided to increase the density of natural fibers by alkali and/or sizing process on the surface of natural fibers and to improve mechanical strength of a biodegradable resin by increasing interfacial adhesion between cellulose derivative and natural fibers. CONSTITUTION: A biodegradable resin composition includes a cellulose derivative including a repeating unit represented by chemical formula 1 and surface-treated natural fibers. In chemical formula 1, R is respectively H or -C(O)-X, wherein X is an alkyl group of carbon number 1-4, except that R is hydrogen. The cellulose derivative is at least one kind selected from the group consisting of cellulose acetate, cellulose diacetate, and cellulose triacetate.
