Abstract
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. In formula (1), R1 to R3 each represent alkyl having 1 to 3 carbon atoms, R4 to R7 each represent alkyl having 1 to 3 carbon atoms or a hydrogen atom, and X− represents an anion of an acid (C).
