（発明が解決しようとする問題点）
電解液は電解コンデンサの陽極電極の誘電体層と集電陰
極との間に介在して、電解コンデンサの直列抵抗を構成
し、この為、電解液の電導塵が低いと、電解コンデンサ
の内部の等価直列抵抗分を増大させ、高周波特性や損失
特性が悪くなる。近年まずまず高度の電気的特性の電解
コンデンサが求められており、現状の電解液の電導塵で
は十分とは言えない。特に現状の電解液の場合、溶質の
０度を十分に高めても所望の電導塵が得られない場合が
多く、その為やむおえず意図的に水を添加して電導塵の
向上を図ることか行われている。水の添加は製品コンデ
ンサの高温での安定性を劣化させる別の問題を提起する
。従って、電導塵と安定性の高い電解液の要望が高い。(Problem to be Solved by the Invention) The electrolytic solution is interposed between the dielectric layer of the anode electrode of the electrolytic capacitor and the current collecting cathode, and constitutes a series resistance of the electrolytic capacitor. A low amount of dust increases the equivalent series resistance inside the electrolytic capacitor, worsening high frequency characteristics and loss characteristics. In recent years, there has been a demand for electrolytic capacitors with reasonably high electrical characteristics, and the current conductive dust in the electrolyte solution is not sufficient. Particularly in the case of current electrolytes, it is often not possible to obtain the desired conductive dust even if the temperature of the solute is sufficiently raised to 0 degrees, so it is unavoidable to intentionally add water to improve the conductive dust. or is being done. Addition of water poses another problem that degrades the high temperature stability of product capacitors. Therefore, there is a high demand for an electrolytic solution with high conductive dust and stability.
それ故、本発明の目的は、非水系、若しくは可及的に非
水系の高電導度の電解液を提供することにより、電解コ

を向上させることを目的としている。Therefore, an object of the present invention is to improve the electrical characteristics of electrolytic capacitors and to maintain stable characteristics for a long time by providing a non-aqueous, or as much as possible non-aqueous, highly conductive electrolyte. The purpose is to improve the reliability of electrolytic capacitors by maintaining them for a long period of time.
