An electrolytic solution capable of improving the high-temperature cycle characteristics of an electrochemical device is provided. An electrolytic solution comprising a compound represented by the general formula (1). General formula (1): [Chemical 1] (In the formula, Rf 101 is CF 2 H— or CFH 2 —. R 101 and R 102 are each independently (i) a C 1-4 alkyl group which may be fluorinated, fluorine An alkenyl group having 2 to 4 carbon atoms which may be formed, or (ii) a carbon-carbon unsaturated bond which is linked to each other to form a 5-membered or 6-membered heterocyclic ring together with a nitrogen atom, and A hydrocarbon group containing at least one of carbon-nitrogen unsaturated bonds, provided that when R 101 and R 102 are the group (i), at least one of them is the alkenyl group, etc. R 101 and R 102 May contain at least one selected from the group consisting of O and N in the structure.)
