Abstract
Disclosed is a biodegradable resin composition containing at least one biodegradable organic high molecular compound, a flame retardant additive containing a phosphorus-containing compound, and a hydrolysis suppressing agent suppressing the hydrolysis of the at least one biodegradable organic high molecular compound. An aliphatic polyester resin is polylactic acid, polycaprolactone, polyhydroxy lactic acid, polyhydroxy valeric acid, polyethylene succinate, polybutylene succinate, polybutylene adipate, polymalic acid, polyesters synthesized by fermentation, or a copolymer containing at least one of them. A polysaccharide is cellulose, starch, chitin, chitosan, dextrane, a derivative of at least one of them, or a copolymer containing at least one of them.
