This non-aqueous electrolyte has good wettability to a polyolefin separator, can provide a battery with excellent load characteristics for a long period, does not easily decompose in the battery under high-temperature storage, and causes little gas generation due to decomposition. Furthermore, a non-aqueous electrolyte secondary battery is provided that includes a positive electrode, a negative electrode, a separator, and the above-described non-aqueous electrolyte.
