PROBLEM TO BE SOLVED: To provide a polyester resin composition having a resol type phenol resin and excellent curability. SOLUTION: The polyester resin composition includes: a polyester resin containing 50 equivalent/ton or more of aromatic rings each of which has a phenolic hydroxyl group and at least one position between ortho positions and a para position to the phenolic hydroxyl group has a hydrogen atom; at least one kind of thermosetting resin chosen from resol type phenol resins; and a curing catalyst chosen among a group composed of sulfuric acid, p-toluenesulfonic acid, dodecylbenzene sulfonic acid, naphthalene sulfonic acid and amine block bodies obtained by neutralizing a part or whole of these acids with an amine compound. The thermosetting resin of 5 to 100 parts by weight and the curing catalyst of 0.01 to 0.5 parts by weight are used based on the polyester resin of 100 parts by weight.
