An object of the present invention is to provide a nonaqueous electrolytic solution capable of improving electrochemical characteristics in a wide temperature range and an electrical storage device using the nonaqueous electrolytic solution. The present invention relates to a non-aqueous electrolytic solution and an electrical storage device. The non-aqueous electrolytic solution is a non-aqueous electrolytic solution in which an electrolyte salt is dissolved in a non-aqueous solvent, and is characterized in that the non-aqueous electrolytic solution contains more than one The cyclic sulfonate compound shown in the general formula (I), wherein, L represents at least one hydrogen atom of the alkylene group is replaced by OR 3 A divalent hydrocarbon group, or at least one methylene group of the alkylene group ( CH 2 ) a divalent hydrocarbon group substituted by a C(=O) group; R 3 represents an alkylcarbonyl group, an alkenylcarbonyl group, and the like. |
