Nonaqueous electrolyte and nonaqueous secondary battery

A nonaqueous electrolyte comprising a lithium salt, an organic solvent having dissolved therein the lithium salt, and at least one compound represented by general formula (1):

• wherein R1, R2, R3, R4, and R5 each independently represent a hydrogen atom, an optionally substituted aliphatic hydrocarbon group having 1 to 20 carbon atoms, a halogen atom, a nitrile group, a nitro group, an amino group, a carboxyl group, a hydroxyl group, a thiol group, a formyl group, a sulfo group, or a phosphate group, the aliphatic hydrocarbon group optionally having the alkylene moiety thereof, inclusive of the moiety bonded to the benzene ring, interrupted by —O—, —CO—, —OCO—, —COO—, —O—CO—O—, —NR—, —S—, —SO—, —SO2—, —NR—CO—, or —CO—NR— at 1 to 3 sites provided that the interrupting groups do not join each other, at least one of R1, R2, R3, R4, and R5 being an aliphatic hydrocarbon group having 1 to 20 carbon atoms substituted with at least one halogen atom;
• R represents a methyl group, an ethyl group, or a propyl group;
• R8 represents an n-valent group;
• R6 and R7 each independently represent an optionally substituted aliphatic hydrocarbon group having 1 to 20 carbon atoms or an optionally substituted aromatic hydrocarbon group having 6 to 20 carbon atoms;
• and
• n represents an integer of 1 to 3.
