PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor and a manufacturing method thereof having good productivity and high reliability. SOLUTION: In the solid electrolytic capacitor having a solid electrolytic capacitor element wherein a pillar-shaped anode 3 consisting of a porous material of a valve action metal from which an anode lead 2 being led out is sequentially formed with a dielectric layer, a solid electrolyte layer 5 consisting of an electrically conductive polymer, and a cathode layer, the thickness of the solid electrolyte layer in the corner portion and the ridgeline portion of the solid electrolytic capacitor element is formed to be equivalent to that in the principal plane portion.
