PROBLEM TO BE SOLVED: To provide an electrolytic solution for aluminum electrolyte capacitors which has both of resistance to voltage and heat resistance.SOLUTION: Provided is an electrolytic solution which comprises; solvent; and an electrolyte dissolved in the solvent and consisting of an α,α'-substituted dibasic acid with a novel dioxa skeleton structure introduced therein. The compound has a hydrocarbon chain structure making a dioxa skeleton which is expressed by the following chemical formula. In the formula, Ris selected from a group consisting of groups having aliphatic rings, such as a branched alkyl group with 4C-16C and a cyclohexane dimethylene skeleton, and groups including aromatic rings, such as a group with an alkylene oxide unit bonded to part of OH group of either end of bisphenol A. |
