摘要： A solid electrolytic capacitor that includes: a laminated body having a plurality of capacitor elements stacked to have principal surfaces thereof overlapped with each other. The capacitor elements each include a valve-action metallic substrate having two principal surfaces opposed to each other, a dielectric oxide film covering a surface of the valve-action metallic substrate, and a cathode layer covering a surface of the dielectric oxide film. The laminated body has two principal surfaces and more than one side surface, and has at least one of the side surfaces with the valve-action metallic substrates exposed. An anode terminal is electrically connected to the side surface of the laminated body having the valve-action metallic substrates exposed therefrom, and the cathode layers and the anode terminal are insulated with insulators interposed therebetween, the insulators being obtained from the cathode layers.

摘要： A solid electrolytic capacitor having grooves provided in a valve-acting metal substrate that includes a porous surface part and a non-porous body part, the bottoms of the grooves being non-porous. The valve-acting metal substrate is divided into a plurality of unit regions by the grooves, and define cathode layer formation parts in the porous surface parts for each unit region. A dielectric layer covers the surfaces of the cathode layer formation parts of the valve-acting metal substrate and the grooves between the cathode layer formation parts. A solid electrolyte layer and a cathode extraction layer cover the surface of the dielectric layer, thereby providing a sheet in which a plurality of solid electrolytic capacitor elements are prepared integrally with the grooves interposed therebetween. The sheet is cut at the grooves, and a dielectric layer is formed on the cut surfaces located around the cathode layer formation parts.
