    摘要: It is provided the electrolytic solution for use in the electrolytic capacitor including a capacitor element and a casing containing said capacitor element, said capacitor element including a pair of electrodes, and a conductive separator (E) which is formed with a conductive polymer layer (F) containing a dopant agent (H) on its surface and is interposed between said pair of electrodes, said conductive separator (E) and said pair of electrodes being rolled up in an overlapped state with each other, and spaces between said pair of electrodes being impregnated with the electrolytic solution for electrolytic capacitor, wherein an acid component (D) and a base component (C) as electrolytic components to be contained in said electrolytic solution are at such a molar ratio that the acid component (D) is excessive. By use of said electrolytic solution for electrolytic capacitor, the increase in the ESR with the elapse of time in an electrolytic capacitor is suppressed.
