PROBLEM TO BE SOLVED: To provide an electrolyte low in impedance characteristic and long in lifetime.SOLUTION: The electrolyte contains a solvent composed of water and an organic solvent, a phosphorus oxo acid ion generation component for generating a phosphorus oxo acid ion in an aqueous solution, a chelating agent coordinated in aluminum for forming a water-soluble aluminum chelate complex, a compound selected from an undecanedioic acid, an undecanedioic acid salt, a dodecanedioic acid, a dodecanedioic acid salt, a tridecanedioic acid and a tridecanedioic acid salt, and a compound selected from formic acid, a formic acid salt, an adipic acid, an adipic acid salt, a glutaric acid and a glutaric acid salt. The compound selected from the undecanedioic acid, undecanedioic acid salt, dodecanedioic acid, dodecanedioic acid salt, tridecanedioic acid, and tridecanedioic acid salt has a saturation dissolution quantity at 50°C at most. |
