摘要： The invention provides a solid electrolytic capacitor wherein the anode has a dielectric oxide film of a structure less susceptible to damage due to mechanical stresses and which is diminished in leakage current and less prone to short-circuiting, and a process for fabricating the capacitor. The capacitor of the invention comprises an anode of aluminum having a dielectric oxide film formed over a surface thereof from amorphous alumina, and is characterized in that a plurality of tunnel-shaped etching pits are formed in the anode. The process of the invention for fabricating the solid electrolytic capacitor includes the steps of forming a plurality of tunnel-shaped etching pits in an aluminum material, effecting anodic oxidation by immersing the aluminum material in an electrolytic solution containing oxalic acid or the like, and effecting anodic oxidation by immersing the aluminum material in an electrolytic solution containing boric acid or like inorganic acid or a salt thereof or containing adipic acid or like organic acid or a salt thereof and applying a voltage at least three times the rated voltage of the capacitor.
