Zusammenfassung:Provided is an electrolyte solution characterized by comprising a specific organic solvent selected from among a chain carbonate represented by general formula (1-1), an ester represented by general formula (1-2), and a phosphate ester represented by general formula (1-3) at a molar ratio of 1-8 with respect to a metal salt in which an alkali metal, an alkali earth metal, or aluminum serves as a cation and a chemical structure comprising two or three elements selected from among boron, carbon, oxygen, halogen, phosphorus, and arsenic serves as an anion. General formula (1-1): R10OCOOR11. General formula (1-2): R12COOR13. General formula (1-3): OP(OR14)(OR15)(OR16).
