Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electrolyte for a nonaqueous electrolyte secondary battery, improved in storage characteristics, and a nonaqueous electrolyte secondary battery including the electrolyte.SOLUTION: An electrolyte contains: a solvent A comprising at least one selected from an ethylene carbonate and a fluoroethylene carbonate; a solvent B comprising at least one selected from a cyclic carbonate having a melting point of -20°C or below and a boiling point of 205°C or above, and a glycol ether having a melting point of -20°C or below and a boiling point of 205°C or above; and a supporting salt. A nonaqueous electrolyte secondary battery includes the electrolyte.
