Summary:Disclosed is an electrolyte solution for electrolytic capacitors, which contains an organic solvent, an additive dissolved in the organic solvent, and an electrolyte. The additive is composed of at least one boric acid ester represented by one of the formula (1), formula (2) and formula (3) below. The electrolyte is composed of an onium cation and an anion of a polyvalent carboxylic acid. Formula (1) Formula (2) Formula (3) In the formulae, an end may be CH3 or H; R1, R2 and R3 respectively represent -CH2O-, -C2H4O-, -C3H6O- or -C4H8O-; and k, l, m and n respectively represent an arbitrary natural number. Cette invention concerne une solution électrolytique pour condensateurs électrolytiques, ladite solution contenant un solvant organique, un additif dissous dans ledit solvant et un électrolyte. L'additif est composé d'au moins un ester de l'acide borique répondant à l'une des formules parmi la formule (1), la formule (2) et la formule (3). L'électrolyte est composé d'un cation onium et d'un anion d'un acide carboxylique polyvalent. Dans les formules ci-dessus, une extrémité peut être CH3 ou H ; R1, R2 et R3 représentent chacun -CH2O-, -C2H4O-, -C3H6O- ou -C4H8O- ; et k, l, m et n représentent chacun un entier naturel arbitraire.
