A resin composition reduced in environmental burden which is excellent in strength, impact resistance, heat resistance, and moldability and which can be produced while attaining a reduction in CO2 discharge amount. The resin composition comprises (A) a styrene resin, (B) an aliphatic polyester, and at least one member selected between (C) a compatibilizing agent and (D) a dicarboxylic anhydride. The compatibilizing agent (C) preferably comprises one or more of the following. (C-1) A polymethyl methacrylate polymer (C-2) A vinyl polymer obtained by copolymerization with an epoxy or an acid anhydride (C-3) A graft polymer obtained by graft-polymerizing methyl methacrylate with a rubbery polymer (C-4) A block copolymer comprising a polylactic acid segment and a vinyl polymer segment bonded thereto |
