【Task】 An electrolytic capacitor having low impedance characteristics and good leaving characteristics is provided. [Solution] In an electrolytic capacitor containing a solvent containing water as a main component, adipic acid or a salt thereof, formic acid or a salt thereof, a chelating agent, and an electrolytic solution for an electrolytic capacitor composed of a compound that generates phosphate ions in an aqueous solution. Since the pH of the electrolyte solution is 5.2 to 6.3, preferably 5.3 to 5.8, it has low impedance characteristics and good standing characteristics. [Selection figure] None |
