PROBLEM TO BE SOLVED: To provide a reliable method for impregnating an aluminum electrolytic capacitor with a driving electrolyte by improving impregnability and fluctuations in capacitance appearance ratio. SOLUTION: The method for impregnating an aluminum electrolytic capacitor with a driving electrolyte is characterized in that a solution type silicone-based antifoam in which silicone oil is dissolved in a solvent or a mixture of silica silicon, polyether, mineral oil, and the like is added to an electrolyte.
