WIPO Patent Application WO/2023/120383
Kind Code:
A1
Abstract:
This electrolytic capacitor is provided with: at least one capacitor element including a positive electrode section and a negative electrode section; an exterior body that seals the capacitor element; and a plurality of external electrodes that are electrically connected to the positive electrode section and the negative electrode section, respectively. An end surface of at least one among the positive electrode section and the negative electrode section of the capacitor element is exposed from at least one outer surface of the exterior body. The exposed end surface and the outer surface are covered with the external electrode. An electroless Ag plating layer covering at least the outer surface is interposed between the outer electrode and the outer surface. The electroless Ag plating layer covers the outer surface through or without a base layer which is a non-plating layer.
