PROBLEM TO BE SOLVED: To provide a polyester resin of excellent heat resistance and impact resistance. SOLUTION: This heat resistant polyester resin is a heat resistant polyester resin (III) constituted of a diol component (I) and a dicarboxylic acid component (II), and having a content of 5-99 mol.% of a bisphenol-A ethylene oxide adduct (A) in the diol component (I). The bisphenol-A ethylene oxide adduct (A) is a reaction mixture comprising 0-1 mol.% of bisphenol-A ethylene oxide one-molar adduct (A1), 92-100 mol.% of bisphenol-A ethylene oxide two-molar adduct (A2), and 0-7 mol.% of bisphenol-A ethylene oxide three-or-more-molar adduct (A3).
