Abstract
A solid electrolytic capacitor element includes an anode body that includes a porous part in at least a surface layer of the anode body, a dielectric layer, and a cathode part. The cathode part includes a solid electrolyte layer that covers the at least a part of the dielectric layer. The anode body includes a first part and a second part. The first part is a cathode forming part on which the solid electrolyte layer is formed, and the second part is a part on which the solid electrolyte layer is not formed. The second part includes at least an anode part including an end of the anode body opposite to the first part. The first part is sectionalized into a plurality of regions, and the first part has a groove at a boundary between adjacent regions among the plurality of regions.
