The present invention provides a non-aqueous electrolyte solution for use in a non-aqueous electrolyte battery excellent in safety during overcharge and high-temperature continuous charge characteristics. A nonaqueous electrolytic solution containing a compound represented by formula (I). (In General Formula (I), R 1 represents a hydrocarbon group having 1 to 12 carbon atoms which may be substituted with a fluorine atom, and R 2 to R 6 are each independently a hydrogen atom, a fluorine atom, or a fluorine atom. Represents an optionally substituted alkyl group having 1 to 12 carbon atoms, and n represents an integer of 0 or 1. However, when n is 0, at least one of R 2 to R 6 is a fluorine atom. Represents an optionally substituted alkyl group having 2 or more carbon atoms, and when n is 1, at least one of R 2 to R 6 represents an alkyl group having 5 or more carbon atoms which may be substituted with a fluorine atom. .)
