Abstract:
1. A solid electrolytic capacitor comprising: an anode formed of a porous sintered body having a corner at one end surface and a corner at the other end surface; an anode lead having one end portion embedded into the anode and the other end portion extending out of the one end surface of the anode; a dielectric layer formed on a surface of the anode; and an electrolyte layer formed on the dielectric layer, wherein the anode includes a first region adjacent to a root of the anode lead, a second region at the corner of the one end surface, a third region between the first and second regions, and a fourth region in the interior of the anode into which the anode lead is embedded, and the thicknesses of the dielectric layer in the first and second regions are greater than the thicknesses of the dielectric layer in the third and fourth regions.
