<p>PROBLEM TO BE SOLVED: To provide a capacitor which is improved in durability by suppressing the eluation of the material of current collecting bodies into the electrolytic solution of the capacitor. SOLUTION: This capacitor is constituted by dipping electrodes 1 which are formed by holding an active material 121 on current collecting bodies 11 composed of a conductive metal in the electrolytic solution 2 containing an inhibitor against elution of metallic ion which inhibits the elution of the conductive metal into the solution 2. When the conductive metal is aluminum or an aluminum alloy and the solution 2 is an organic solution, it is preferable to use one or more kinds selected out of benzoic acids and their salts and esters as the inhibitor. It is particularly preferable to use methyl benzonate as the inhibitor.</p> |
