Abstract
The object of the present invention is to provide a nonaqueous electrolytic solution that can improve the electrochemical properties in a broad temperature range and an electrochemical device using the same. A nonaqueous electrolytic solution prepared by dissolving an electrolyte salt in a nonaqueous solvent, wherein the nonaqueous solvent includes 0.1 to 30% by volume of a fluorine atom-containing cyclic carbonate, and further the nonaqueous electrolytic solution includes 0.001 to 5% by mass of a branched dinitrile compound in which the main chain of an alkylene chain linking the two nitrile groups has 2 or more and 4 or less of the carbon number.
