An object of the present invention is to provide a polyester resin excellent in moldability, surface smoothness, transparency, mechanical characteristics, and heat-resistance, with reduced generation of gel. The present invention relates to a polyester resin comprising a constituent moiety derived from dicarboxylic acid component and a constituent moiety derived from alcohol component, wherein a content of a compound represented by Formula (I) is 0.0002 to 5.9% by weight in 100% by weight of the alcohol component. In the Formula (I), m and n each represent 1 to 1000, 1 represents 0 to 1000, R1 represents an aromatic hydrocarbon group having 6 to 20 carbon atoms, and R2, R3, and R4 each represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms.
A polyester resin comprising a constituent moiety derived from a dicarboxylic acid component and a constituent moiety derived from an alcohol component that comprises a compound represented by Formula (I),
