Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lithium ion capacitor which operates stably even at a high voltage. SOLUTION: An ionic compound for additive is used together with a main electrolyte in an electrolyte of an electric storage device. The additive is expressed by general formula (1):Kt+[B(CN)4]-(in the formula (1), Kt+expresses an onium cation and/or inorganic cation). The additive of not less than 0.01 mass% and less than 50 mass% is used with respect to a total of the main electrolyte and additive of 100 mass%. COPYRIGHT: (C)2011,JPO&INPIT
