The present invention provide a nonaqueous electrolyte comprising a nonaqueous solvent, wherein the nonaqueous solvent includes ethylene carbonate (EC), propylene carbonate (PC), -butyrolactone (GBL) and a fourth component that is a solvent other than the EC, the PC and the GBL, and the nonaqueous solvent satisfies the following equations (1) to (4):

15 x 50	(1)	30 y 75	(2)	0 z 30	(3)	0 p 5	(4)

where, the x is a ratio (volume %) of ethylene carbonate to a total volume of the nonaqueous solvent, the y is a ratio (volume %) of propylene carbonate to the total volume of the nonaqueous solvent, the z is a ratio (volume %) of -butyrolactone to the total volume of the nonaqueous solvent, and the p is a ratio (volume %) of the fourth component to the total volume of the nonaqueous solvent.
