PROBLEM TO BE SOLVED: To provide a polyester resin molded item which has a small molding shrinkage ratio in molding and a small heat shrinkage ratio after a heat treatment, gives a molded article having improved dimensional stability, exhibits excellent molding property and has a characteristic of low specific gravity. SOLUTION: The polyester resin molded item comprises a polyester resin composition obtained by melt-kneading and compounding a polybutylene terephthalate resin with a polycarbonate resin and has a controlled structure of a two-phase continuous structure having a structural period of 0.001-1μm or a dispersed structure having an interparticle distance of 0.001-1μm.
