ABSTRACT:
An electrolytic solution for use in an electrolytic capacitor including a capacitor element and a casing containing the capacitor element, the 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 the pair of electrodes, the conductive separator (E) and the pair of electrodes being rolled up in an overlapped state with each other, and spaces between the pair of electrodes being impregnated with the electrolytic solution, wherein an acid component (D) and a base component (C) as electrolytic components to be contained in the electrolytic solution are at such a molar ratio that the acid component (D) is excessive. By use of the electrolytic solution, increase in the ESR with the elapse of time in an electrolytic capacitor is suppressed.
