An object of the present invention is to provide a biodegradable polyester resin composition having excellent mechanical strength, heat resistance, and flexibility, and having rheological properties advantageous for molding a foam or the like, a method for producing the same, and a molded article thereof. A biodegradable polyester resin (a) containing 50 mol% or more of α- and / or β-hydroxycarboxylic acid units, and a biodegradable aliphatic-aromatic copolymer having a glass transition temperature of 0 ° C. or less. It consists of a polyester resin (b) and a (meth) acrylate compound (c), and the mass ratio (a / b) of (a) and (b) is 99/1 to 20/80 (mass%). A biodegradable polyester resin composition, wherein (c) is 0.01 to 20 parts by mass based on a total of 100 parts by mass of (a) and (b). [Selection diagram] None |
