Abstract: A method for manufacturing a positive electrode for a power storage device includes the steps of: preparing a current collector that includes a first region and a second region on a surface of the current collector, the first region having a carbon layer formed on the surface, the second region having the surface exposed; and forming a conductive polymer layer selectively on a surface of the carbon layer by immersing the current collector in an electrolytic solution containing a raw material monomer and then conducting electrolytic polymerization of the raw material monomer.
