PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic solution hardly causing generation of an excess coat on a negative electrode active material and having good cycle characteristic.SOLUTION: The nonaqueous electrolytic solution contains: a nonaqueous solvent; an electrolyte; a halogenated cyclic carbonate; thiol compound represented by a following formula 1 [R1, R2, R3 are hydrogen, or an alkyl group (-CH,n=1 to 4), a carboxy group, a carboxylate group (-COO), an alkoxycarbonyl group (-COOR4), an amino group (-NH, -NHR5, -NR5R6, R5, R6 are alkyl groups, carboxy groups carboxylate groups (-COO)), and a sulfanil group]. The thiol consists of a compound containing at least any one of the carboxy group, the carboxylate group and the amino group. |
