<p>An electrolysis solution for electrolytic capacitors comprising an aqueous organic solvent consisting of water and a water-compatible organic solvent and 1,6-decanedicarboxylic acid or a salt thereof dissolved therein, which solution further contains one or more additives selected from the group consisting of dinitriles, pivalic acid and salts thereof, diesters, alkylated lactones, cyanoalkanoic esters, monocarboxylic acids each having a C3-7 alkyl chain and being substituted with two C1-4 alkyl groups at the beta -position to the carboxyl group and salts thereof, monocarboxylic acids each having a C3-7 alkyl chain and being substituted with one ethyl group at the alpha -position to the carboxyl group and salts thereof, and monocarboxylic acids derived from cyclic saturated compounds each having five or six ring-constituting carbon atoms and salts thereof. When one or more compounds selected from among dinitriles, diesters, alkylated lactones and cyanoalkanoic esters are used as the additives, the 1,6-decanedicarboxylic acid may be replaced by other carboxylic acid.</p> |
