Provided is an electrolytic solution capable of improving high temperature storage characteristics and cycle characteristics of an electrochemical device. The following general formulas (1-1) (in the formula, Rf111 is the same or different fluorinated alkenyl group having 2 to 4 carbon atoms), (1-2) (in the formula, R121 has 1 carbon atom). It is an alkyl group of ~ 4, Rf121 is a fluorinated alkenyl group having 2 to 4 carbon atoms.) And (1-3) (in the formula, Rf131 is a fluorinated alkyl group having 1 to 3 carbon atoms. , R131 is an electrolytic solution containing at least one selected from the group consisting of compounds represented by (an aryl group having 6 to 12 carbon atoms).
