Disclosed are a non-aqueous electrolytic solution that exhibits excellent electrochemical characteristics over a wide temperature range, and an electrochemical device using the non-aqueous electrolytic solution. The non-aqueous electrolytic solution includes a non-aqueous solvent and an electrolyte salt dissolved in the non-aqueous solvent, wherein the non-aqueous electrolytic solution further comprises one compound represented by general formula (I):
wherein R 1 represents alkyl having 1 to 6 carbon atoms, cycloalkyl having 3 to 6 carbon atoms, alkenyl having 2 to 6 carbon atoms, alkynyl having 3 to 6 carbon atoms, or aryl having 6 to 12 carbon atoms; X represents a divalent linking group that has 1 to 6 carbon atoms and is optionally substituted by a halogen atom; and Y 1 represents a specific substituent, for example, alkylcarbonyl. |
