Abstract

Provided is a thermoplastic resin composition having high flame resistance, high fluidity during injection molding, and improved impact resistance in a molded article. To provide a method for producing a thermoplastic resin composition, the method including a step (1) of obtaining a polyester resin mixture by melt-kneading a crystalline terephthalate-based polyester resin, and a polyester resin A including at least one kind selected from the group consisting of isophthalic acid, orthophthalic acid, naphthalenedicarboxylic acid, anthracene dicarboxylic acid and pyridine dicarboxylic acid as an aromatic dicarboxylic acid component with an extruder, and a step (2) of mixing the polyester resin mixture, a polycarbonate resin, a flame retardant and a toughening agent.
