Abstract
Provide is an aluminum electrolytic capacitor exhibiting low specific resistance and low impedance property and realizing high reliability. An electrolytic capacitor has a structure in which: a capacitor element which is formed by rolling an anode foil and a cathode foil each connected with an electrode extraction lead through a separator and which is impregnated with a drive electrolytic solution is included in a cylindrical outer case having a closed-end; and an open end of the outer case is sealed with an elastic sealing body, in which: the drive electrolytic solution contains a tricyanomethide salt represented by the below-indicated chemical formula (1); and the drive electrolytic solution has a water content of 3.0 wt % or less: where, R represents a cation pairing with a tricyanomethide ion in formation of a tricyanomethide salt.
