PROBLEM TO BE SOLVED: To provide a polyester resin composition which, despite inclusion of a recycled polyester resin, enables production by molding of a polyester resin molded article with excellent dimentional stability and excellent surface properties.SOLUTION: Provided is a polyester resin composition comprising a recycled polyester resin and a dimensional stabilizer. The dimensional stabilizer is a thermally expandable microsphere comprising an outer shell comprising a thermoplastic resin obtained by polymerizing polymerizable components including a carboxyl group-containing monomer, in which is included a foaming agent which evaporates upon heating. The polyester resin molded article is formed by molding the polyester resin composition. |
