To provide a method for manufacturing a capacitor capable of manufacturing a capacitor having low inductance and excellent high frequency characteristics at low cost while simplifying the manufacturing process of a multi-terminal solid electrolytic capacitor. A step of forming a capacitor dielectric film by anodizing one main surface of a metal foil, a step of forming a polymer conductive material layer on the capacitor dielectric film, and the metal foil A step of forming a through-hole 30 in 20, a step of attaching a support base 40 to the other main surface 20b of the metal foil 20, a step of filling the through-hole 30 with an insulating material 43, and a polymer conductive material layer The step of flattening the insulating material 43 so as to expose 22, the step of sticking the base material 25 with the conductive layer 26 formed on the flattened surface, and the insulation with the support base material 25 removed And a step of forming an electrode extraction hole 45a in the material 43.
