Abstract
A solid electrolytic capacitor that includes: a valve-action metal substrate including a porous portion at a surface thereof; a dielectric layer on the porous portion; a solid electrolyte layer on the dielectric layer; a conductive layer on the solid electrolyte layer; and a cathode lead-out layer on the conductive layer. When viewed in a thickness direction, the solid electrolyte layer includes a central region at a center of the solid electrolyte layer and a peripheral region surrounding the central region and defining outer edges of the solid electrolyte layer. The peripheral region is higher than the central region in the thickness direction as measured from a reference surface including a highest point of the porous portion in the thickness direction and perpendicular to the thickness direction. The conductive layer is at least on the central region of the solid electrolyte layer.
