A non-aqueous electrolyte that realizes a non-aqueous secondary battery in which decomposition of the electrolytic solution is suppressed in a long-term charge / discharge cycle even when used in a battery driven at a high voltage, and electrolysis for a lithium ion secondary battery And a non-aqueous electrolyte battery comprising the non-aqueous electrolyte or the lithium-ion secondary battery electrolyte. An unsaturated bond-containing carbonate compound, an organic chlorine-containing compound of 0.05 to 1% by mass with respect to 100% by mass of the unsaturated bond-containing carbonate compound, an inorganic acid, an organic acid, an acid amide, and an amine A nonaqueous electrolytic solution comprising a silicon-containing compound in which one or more hydrogen atoms of one or more compounds selected from the above are substituted with a silicon-containing functional group, and a lithium salt.
