(57) Abstract: Provided is a non-aqueous electrolyte having excellent battery life, charge / discharge characteristics, load characteristics, and low-temperature characteristics, and a secondary battery using the same. A non-aqueous electrolytic solution comprising a non-aqueous solvent containing a phenylenedicarbonate derivative represented by the following general formula [1] and an electrolyte. Embedded image (R 1 and R 2 may be the same or different and represent a hydrocarbon group having 1 to 11 carbon atoms, and R 3 has 1 to 11 carbon atoms. 11 hydrocarbon groups, C1-11 alkyloxy groups, C1-11 aryloxy groups or C1 -9 represents an alkylsilyloxy group, and n is an integer of 0-4. ) |
