Abstract: An electrolytic capacitor includes a capacitor element that includes an anode part and a cathode part, an exterior body that seals the capacitor element, a first external electrode that is electrically connected to the anode part, and a second external electrode that is electrically connected to the cathode part. At least one of an end face of the anode part or an end face of the cathode part is exposed from the exterior body to be electrically connected to a corresponding one of the first external electrode or the second external electrode. The end face exposed from the exterior body is covered with an electroless Ni plating layer, and the electroless Ni plating layer is covered with an electroless Ag plating layer. The electroless Ag plating layer is covered with the corresponding one of the first external electrode or the second external electrode.
