Abstract
A manufacturing method according to the present invention of a solid electrolytic capacitor includes: a step of immersing a anode body on which the dielectrics film layer is formed in a solution that includes from 0.7 to 10% by weight of hydrogen peroxide, from 0.3 to 3% by weight of sulfuric acid and water as a main solvent, followed by, after pulling up, exposing to vapor of pyrrole or a pyrrole derivative, and thereby forming, on the dielectrics film layer, a first conductive polymer layer made of polypyrrole or a polypyrrole derivative; and a step of immersing the anode body on which the dielectrics film layer and the first conductive polymer layer are formed in a solution that includes a polymerizing monomer and a supporting electrolyte to electrolytically polymerize the polymerizing monomer, and thereby forming a second conductive polymer layer on the first conductive polymer layer.
