デンサの容量減少を抑制することのできる電解液に関す
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electrolytic solution for driving an electrolytic capacitor, and particularly to an electrolytic solution that can suppress a decrease in capacitance of a capacitor.
（従来の技術およびその問題点）

媒に有機カルボン酸のアンモニウム塩またはアミン塩を
溶解して使用している。(Prior Art and its Problems) Generally, as a low-pressure electrolyte of 100 WV or less, an ammonium salt or amine salt of an organic carboxylic acid is dissolved in a polar organic solvent such as ethylene glycol or T-butyrolactone.
また、電解コンデンサは表面を粗面化した後、陽極酸化

してない陰極箔とをセパレータを挟んで巻回し、電解液
を含浸した後、金属ケース等に密封して構成される。In addition, electrolytic capacitors are made by winding an anode foil, which has a roughened surface and then anodized to form a dielectric film, and a cathode foil, which does not have a dielectric film, with a separator in between, and impregnates it with an electrolyte. After that, it is sealed in a metal case or the like.

サ中で電解液と接触すると、容量が著しく減少してしま
うことがある。In extremely low-voltage capacitors where the working voltage is 10 WV or less, the cathode foil used is required to have a large capacity, but even then, the ratio with the anode foil capacity is insufficient, so the cathode foil capacity accounts for less than the total capacity. The effect is large, and since the cathode foil is generally not anodized, there is only a thin natural oxide film on the surface. Therefore, when it comes into contact with an electrolyte, especially in an electrolytic capacitor, the capacitance may be significantly reduced.
従って、極低圧コンデンサにおいては静電容量の経時変
化、特に容量減少が大きいことが問題であった。Therefore, in extremely low voltage capacitors, it has been a problem that the capacitance changes over time, especially the capacitance decreases greatly.
