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
