The present invention relates to a polyester resin composition and a molded product thereof. The polyester resin composition is obtained by compounding at least: (A) 100 parts by mass of a polybutylene terephthalate resin, (B) 15 to 100 parts by mass of an amorphous resin and (C) 0.01 to 5 parts by mass of an epoxy resin with a special structure, and the melting point of the polyester resin composition is greater than 210°C but less than 221°C. The polyester resin composition and the molded product thereof according to the present invention have excellent laser transmittance and can be used for various electrical mounting components for automobiles (various control units, various sensors, etc.), connectors, switch components, relay components, etc.
