PROBLEM TO BE SOLVED: To provide a process for fabricating a solid electrolytic capacitor excellent in electric characteristics and having a masking structure which can prevent chemical conversion treatment liquid from oozing up to the positive electrode of the solid electrolytic capacitor during chemical conversion treatment, and can insulate solid electrolyte (negative electrode portion) formed in a subsequent process from the positive electrode certainly. SOLUTION: In the process for fabricating a solid electrolytic capacitor element comprising a step for forming a masking on a part of a positive electrode substrate having a dielectric film on the surface to section that surface, and forming a solid electrolyte layer in at least a partial region on the surface of the positive electrode substrate sectioned by masking, a step performing formation processing in a region including the fringe of masking after forming the masking is included.
