Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new aromatic sulfonic acid ester and a sulfonated polyarylene polymer, imparting high proton conductivity and enabling designing a material with suppressed swelling even under high temperature and humidified conditions. SOLUTION: The new aromatic sulfonic acid ester derivative is provided, being represented by general formula (1). In general formula (1), X is an atom or a group selected from the group consisting of a halogen atom except fluorine (i.e. chlorine, bromine or iodine), -OSO2CH3and -OSO2CF3; Y is -CO- or -SO2-; Z is a direct bond, -CO-, -SO2- or -SO-; n is an integer of 2-5; and R is a 4-20C hydrocarbon group.
