摘要： Provided is a nonaqueous electrolyte solution for a lithium secondary battery, the nonaqueous electrolyte solution containing a compound (I) represented by Formula (I) and a compound (II) represented by Formula (II). In Formula (I), each of R 1 and R 2 independently represents a substituent such as an alkyl group having from 1 to 7 carbon atoms, which optionally contains at least one di- to hexa-valent heteroatom in its structure, and in which at least one hydrogen atom is optionally substituted with a fluorine atom or a functional group having from 0 to 7 carbon atoms. In Formula (II), R 3 represents an oxygen atom or the like; R 4 represents a group represented by Formula (ii-1), a group represented by Formula (ii-2), or the like; and * represents a binding position. In Formula (ii-1), R 41 represents an oxymethylene group or the like and, in Formula (ii-2), R 42 represents an alkyl group having from 1 to 6 carbon atoms, or the like.
