Abstract: An electrochemical device positive electrode with a lead member includes a positive electrode and a lead member attached to the positive electrode. The positive electrode includes a positive current collector, a carbon layer, and an active layer. The carbon layer is disposed on a surface of the positive current collector, and contains a conductive carbon material. The active layer is supported by the positive current collector via the carbon layer disposed between the active layer and the positive current collector, and contains a conductive polymer. The lead member is in contact with the carbon layer.

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.
