Abstract: PROBLEM TO BE SOLVED: To suppress the generation of the defects of an oxide film by immersing and processing a sintered body into hydrogen peroxide before the sintering of metal powder, having valve action and the chemical conversion treatment of the sintered body. SOLUTION: An organic binder, which is fused in solvent, is added to the tantalum-metal powder as minute as possible, and the specified shape is molded together with an anode lead. The material is dried and consolidated. When the consolidated material is burned, the sintered body is obtained, and the most part of the binder is dispersed. Then, the sintered body is immersed into the hydrogen peroxide liquid or 10 wt.% or more and dried. The sintered body after the finish of the hydrogen peroxide liquid processing undergoes chemical conversion treatment. Then, for the sintered body, manganese nitride or the aqueous solution, wherein ammonium nitrate is added into the manganese nitrate, is impregnated in it. The manganese nitrate undergoes thermal decomposition. A manganese dioxide layer is formed on the oxide film.  Thereafter, when the manganese dioxide is grow, a graphite layer is formed on the surface of the sintered body. A silver layer is further formed thereon. A cathode lead is soldered to the silver layer.
