<P>PROBLEM TO BE SOLVED: To provide an electrolyte which is excellent in performance in a low temperature environment and has a high breakdown voltage, and also provide an electrochemical element which can be used stably even at low temperature and is excellent in long-term stability. <P>SOLUTION: The electrolyte contains an electrolyte (B) having a compound (A) expressed by formula (1) and a nonaqueous mixture solvent (H). The nonaqueous mixture solvent (H) contains at least one kind of sulfolane derivative (S) selected from a group of sulfolane, 3-methylsulfolane and 2,4-dimethylsulfolane and also contains at least one kind of nonaqueous solvent (G) selected from a group of ester, benzene derivative and nitrile derivative. <P>COPYRIGHT: (C)2010,JPO&INPIT |
