摘要: Provided is a non-aqueous electrolyte containing a non-aqueous electro solvent and a lithium salt, wherein the non-aqueous solvent includes a carbonate solvent, the lithium salt contains a fluorine-containing cyclic sulfonylimide salt represented by general formula (1): (in the formula, R f each may be the same or different and each represent a fluorine atom or a C4 or lower perfluoro group), and a fluorine-containing sulfonamide compound represented by general formula (2): H(CR 2 ) m -SO 2 NHM 2 (in the formula, R each may be the same or different and each are a fluorine atom or a trifluoromethyl group, M 2 is Li, Na, K, H, or NH 4 , and m is 1 or 2) is contained in an amount of 1,000 mass ppm or less relative to the total amount of non-aqueous electrolyte.
