An object of the present invention is to provide a polyester resin composition having a high glass transition temperature and low crystallinity, that is, excellent in heat resistance and transparency, and hardly colored during molding. A polyester resin comprising a dicarboxylic acid structural unit and a diol structural unit, wherein 1 to 60 mol% of the diol structural unit is a diol unit having a cyclic acetal skeleton, and 100 parts by weight of the polyester resin is a phenolic resin. A polyester resin composition comprising 0.02 to 10 parts by weight of at least one selected from an antioxidant, a sulfur antioxidant, a phosphorus antioxidant, and an aromatic amine antioxidant.
