摘要： A solid electrolytic capacitor that includes a capacitor element including an anode portion having a metal layer, a dielectric layer, and a cathode portion having a solid electrolyte layer and a current collector layer; a leading conductor layer; an insulating resin body covering the capacitor element and the leading conductor layer, the insulating resin body having a first end surface and a second end surface opposite to each other; a first external electrode; and a second external electrode. The first external electrode has at least one plating layer on the first end surface, and is connected to the leading conductor layer at the first end surface. The second external electrode has at least one plating layer on the second end surface, and is connected to the metal layer at the second end surface.

摘要： A solid electrolytic capacitor that includes a plurality of capacitor elements each including an anode portion, a dielectric layer, and a cathode portion having a solid electrolyte layer and a current collector layer; a leading conductor layer; an insulating resin body; a first external electrode; and a second external electrode. The plurality of capacitor elements are stacked in layers, with mutually adjacent capacitor elements having their respective current collector layers connected to each other. The current collector layer of only the capacitor element adjacent to the leading conductor layer is connected to the leading conductor layer. The first external electrode is connected to the leading conductor layer at the first end surface.
