酸又はその塩を加えた電解液が用いられている。<Prior Art> In general, the characteristics of the electrolytic solution used in electrolytic capacitors, such as resistivity and spark voltage, have a great influence on the characteristics of electrolytic capacitors. For example, electrolytic capacitors for medium and high voltages are required to have excellent voltage resistance characteristics and be stable against deterioration due to storage. An electrolyte containing salt is used.

っている。In the above example, an aluminum dry electrolytic capacitor with a rated voltage of 400 V and a rated old-fashioned 1200 μF was manufactured using an electrolytic solution containing 930 q of ethylene glycol, 70 q of ammonium decane dicarboxylate, and 0.5 to 9.5 g of ammonium dodecane diate, and the impedance characteristics were determined. When measured, the results shown in the figure were obtained. The amount of ammonium dodecanoate added is as follows: Conventional example Δ is Og, Example B is 0.50, Example C is 2 g, * Example is 6 g, Example E
is 9.59. As is clear from the figure, 1K)-I
The impedance is reduced by the present invention in the frequency range above z, and in particular, the impedance in the example and E is 10 KHz ~
In the 200 KHz region, it is less than 1/2 that of conventional example A.

５ｗｔ％が好ましい。J5, the amount of ammonium dodecanoate added is 0.
If it becomes 0.5 wt'% unvortexed, the effect of improving high frequency characteristics will be low, and if it is added in excess of 0.95 wt'%, crystallization will start when stored at room temperature, so it is generally 0.05 to 0.9
5 wt% is preferred.
