ける信頼性が著しく低下するなどの課題があった。Problems to be Solved by the Invention In recent years, as aluminum electrolytic capacitors have become lower in impedance, smaller in size, and more reliable, there has been a demand for electrolytic solutions that have low specific resistance and are stable over a wide temperature range. In some electrolytic solutions made by dissolving organic acids or their salts in ethylene glycol and water as main solvents, the proportion of water in the electrolytic solution is increased in order to lower the resistivity. When the blending ratio was increased, there were problems such as a significant decrease in reliability under a high temperature atmosphere.
