[Problem] To provide a method for synthesizing a polyester using an organic catalyst, with which a high-molecular weight polyester can be synthesized at a low temperature. [Solution] A polyester is synthesized using, as a catalyst, a lower bis(perfluoroalkanesulfonyl)imide represented by general formula (I) or a lower perfluoroalkanesulfonic acid represented by general formula (II). In general formulae (I) and (II), Rf represents a straight or branched-chain perfluoroalkyl group having 1 to 10 carbon atoms. |
