    摘要： An electrolysis solution for electrolytic capacitors including an aqueous organic solvent consisting of water and a water-compatible organic solvent and 1,6-decane-dicarboxylic acid or salt thereof dissolved therein. The solution further contains one or more additives selected from dinitriles, pivalic acid and salts thereof, diesters, alkylated lactones, cyanoalkanoic esters, monocarbboxylic acids each having a C3-7 alkyl chain and substituted with two C1-4 alkyl groups at the &bgr;-position to the carboxyl group and salts thereof, monocarboxylic acids each having C3-7 alkyl chain and substituted with one ethyl group at the &agr;-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.
