PROBLEM TO BE SOLVED: To provide a biodegradable resin composition which exhibits biodegradability, is excellent in mechanical strength such as elastic modulus, is excellent in long-term durability, and is finally biodegradable. SOLUTION: Water-insoluble biodegradable resin 100 such as aliphatic polyester, polyamino acid, polyamide / polyester copolymer, polypeptide, lignin and cellulose. Parts by weight, and 0.1 to 50 parts by weight of the layered silicate, the layered silicate has an average interlayer distance of the (001) plane measured by a wide-angle X-ray diffraction method of 3 nm or more, and A biodegradable resin composition which is a layered silicate in which part or all is dispersed in 5 layers or less. |
