Zusammenfassung:Provided are an electrolytic solution for an electric double layer capacitor capable of providing an electric double layer capacitor having stable quality, an electric double layer capacitor using the electrolytic solution, and a manufacturing method for the electric double layer capacitor. The electrolytic solution includes a supporting electrolyte, sulfolane, and a linear sulfone. It is preferred that the electrolytic solution further include an organic fluorine compound. Further, it is preferred that the supporting electrolyte contain 5-azoniaspiro[4.4]nonane tetrafluoroborate, and the content of 5-azoniaspiro[4.4]nonane tetrafluoroborate be 1.5 to 3.6 mol/dm3.
