PROBLEM TO BE SOLVED: To provide an electrolyte for driving an electrolytic capacitor capable of inhibiting radical chain thermal oxidation reaction for a long term only with a small quantity of chemical added without dropping spark generating voltage of the electrolytic capacitor, and capable of inhibiting an increase in a rate of capacitance change and tanδwhile inhibiting an increase in specific resistance of the electrolyte. SOLUTION: The electrolyte for driving the electrolytic capacitor dissolves polyhydric alcohol such as ethylene glycol as a solvent, and carbonic acid, boric acid, ammonium borate, mannitol, sorbitol or the like as a solute, as well as ferulic acid or caffeic acid or their salt.
