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.
