A solid electrolytic capacitor includes an anode element made of a valve action metal, a dielectric oxide film formed on a surface of the anode element, a solid electrolytic layer formed on a surface of the dielectric oxide film, and a cathode layer formed on a surface of the solid electrolytic layer. The solid electrolytic layer has an iron concentration not greater than 100 ppm. Alternatively or in combination therewith, a weight fraction of residues in the solid electrolytic layer is smaller than 5 wt %. The polymerization residue is an oxidizing agent and a monomer that is produced when such solid electrolytic layer is formed.

Solid electrolytic capacitor

An apparatus for manufacturing a solid electrolytic capacitor includes an anodization part, a polymerization part, a cathode layer formation part, an assembly part, and a molding part. The polymerization part includes a plurality of polymerization baths of a substantially same structure and a conveyance mechanism. In addition the plurality of polymerization baths are placed around the conveyance mechanism within a conveyance range.
