PROBLEM TO BE SOLVED: To retain flame retardancy of a water-containing electrolytic solution for electrolytic capacitors over a long term.SOLUTION: An electrolytic solution for electrolytic capacitors comprises a nonhalogen-based phosphazene compound which is dispersed therein. Particularly, to keep its uniform dispersion over a long term, the electrolytic solution is prepared into a Bingham fluid or pseudo plastic fluid by adding a gelatinizer thereto, or the nonhalogen-based phosphazene compound is mechanically made into microparticles (e.g. 300 μm or smaller in particle diameter).SELECTED DRAWING: None |
