摘要： The present invention aims to provide a solvent for an electrolytic solution of electrochemical devices which is chemically stable at high temperatures over a long period of time and is stably liquid at low temperatures. The present invention relates to a solvent for an electrolytic solution of electrochemical devices, including: a cyclic sulfone compound represented by the formula (1): wherein R is a hydrogen atom or a linear or branched C1-C6 alkyl group; a chain alkyl sulfone compound represented by the formula (2) : wherein R 1 and R 2 each independently represent a linear or branched C1-C5 alkyl group, and may be the same as or different from each other; and at least one of an organic amine compound and 4-tert-butylcatechol.
