    Abstract: The present invention provides a foamed molded article production method that can produce polycarbonate resin foamed blow-molded articles, etc. which are good over a wide range of densities. The present invention is a method for producing a foamed molded article including extruding a foamable molten resin, formed by kneading a polycarbonate resin, a polyester resin in an amount of 5 to 100 parts by weight per 100 parts by weight of the polycarbonate resin and a foaming agent, from a die to obtain a foamed parison, and molding the foamed parison in a softened state in a mold. The polyester resin is a polyester copolymer containing diol component units, 10 to 80 mol % of which are glycol component units each having a cyclic ether structure, and dicarboxylic acid component units.
