Abstract
A solid electrolytic capacitor includes a plurality of capacitor elements that are laminated with each other. The plurality of capacitor elements each include an anode body, a solid electrolyte layer, and a cathode lead-out layer. The anode body is a foil-shaped electric conductor having a first main surface and a second main surface opposite to the first main surface. The anode body includes an anode section, a cathode formation section, and a separation section interposed between the anode section and the cathode formation section. The solid electrolyte layer and the cathode lead-out layer are disposed on both the first and the second main surfaces of the cathode formation section. A first insulating layer is disposed on the first main surface of the separation section. A first capacitor element and a second capacitor element that are adjacent to each other among the plurality of the capacitor elements are stacked so that the first insulating layer in the first capacitor element faces the second main surface of the separation section in the second capacitor element.
