Beschreibung
Zusammenfassung:	The present invention provides an electrolyte for an electric double layer capacitor capable of obtaining an electric double layer capacitor with stable quality, an electric double layer capacitor using the same, and a manufacturing method thereof. The electrolyte contains support salt, sulfolane, and chain sulfone. Also, the electrolyte is preferable to contain an organic fluorine compound. The support salt contains 5-azoniaspiro[4.4]nonanetetrafluoroborate. Content of 5-azoniaspiro[4.4]nonanetetrafluoroborate is 1.5 to 3.6 mol/dm^3. (과제)안정된 품질의 전기 이중층 커패시터를 얻을 수 있는 전기 이중층 커패시터용의 전해액, 이것을 이용한 전기 이중층 커패시터 및 그 제조 방법을 제공한다. (해결 수단)지지염과, 술포란과, 쇄상 술폰을 함유함으로써 이루어 진다. 또한, 유기 불소 화합물을 함유하는 것이 바람직하고, 상기 지지염은, 5-아조니아스피로[4.4]노난테트라플루오로보레이트를 함유하고, 5-아조니아스피로[4.4]노난테트라플루오로보레이트의 함유량은, 1.5~3.6㏖/dm인 것이 바람직하다.
