Abstract
An electrolyte solution for use in an electrolytic capacitor. The solution comprises as a solute at least one quaternary ammonium salt of a carboxylic acid selected from the group consisting of PA1 (a) quaternary ammonium salts of maleic acid and/or citraconic acid, PA1 (b) quaternary ammonium salts of aromatic carboxylic acids, and PA1 (c) quaternary ammonium salts of branched-chain aliphatic dicarboxylic acids having 11 to 30 carbon atoms in total. This electrolyte solution has high electric conductivity.
