摘要： In order to render an electrolytic solution not leak from a sealed part even at a higher temperature of the environment or in a high-humidity condition to enhance the reliability of an electrolytic capacitor, an electrolytic solution for an aluminum electrolytic capacitor is described. The electrolytic solution includes an aprotic solvent (A), an electrolyte (D) containing a salt composed of a cation (B) represented by formula (1) and an anion (C), and a compound (E) represented by formula (2) and having a content of 0.01 to 3 wt% relative to the total weight of (A) and (D): wherein in formulae (1) and (2), R 1 to R 3 are each C 1-3 alkyl, R 4 to R 7 are each C 1-3 alkyl or a hydrogen atom, and R 8 to R 14 are each C 1-3 alkyl or a hydrogen atom.

摘要： An issue of this invention is to enhance reliability of an electrolytic capacitor in a manner that an electrolytic solution does not leak from a sealed part while a high initial electrical conductivity is maintained even at a higher environment temperature or in a high-humidity condition. An electrolytic solution for aluminum electrolytic capacitor is described, containing a solvent (A) and an electrolyte (D) represented by general formula (1) below, wherein the content of at least one compound (E) selected from compounds (E1) to (E3) represented by general formulae (2) to (4) below is not more than 3 wt% relative to the total weight of (A) and (D). In formula (1), R 1 to R 3 each represent alkyl having 1 to 3 carbon atoms, R 4 to R 7 each represent alkyl having 1 to 3 carbon atoms or a hydrogen atom, and X - represents an anion of an acid (C). In formula (2), R 8 is alkylene having 1 to 3 carbon atoms, R 9 to R 12 are each alkyl having 1 to 3 carbon atoms or a hydrogen atom, and R 11 and R 12 may be covalently bonded.
