Claim Text:
1. A solid electrolytic capacitor comprising: a porous sintered body made of a valve metal; a dielectric layer formed on the porous sintered body; a solid electrolyte layer formed on the dielectric layer; and a cathode layer formed on the solid electrolyte layer; wherein the solid electrolyte layer includes an inner electrode layer and an outer electrode layer, the inner electrode layer covering the dielectric layer inside the porous sintered body, the outer electrode layer covering the inner electrode layer outside the porous sintered body, the outer electrode layer comprises a solid particle containing layer including a conductive polymer dispersion material and solid particles, the solid particle containing layer being formed by applying a dispersion material liquid containing the conductive polymer dispersion material, the solid particles and a solvent to the inner electrode layer and then removing the solvent, and a ratio of length to thickness of each of the solid particles is 1:X, where 0.05≦X≦0.3.
