Abstract: A flexible conductive polyimide substrate with a fine wiring and a method for manufacturing the same is provided to manufacture a higher value-add flexible conductive polyimide by using an electroless planting and additive method before electroplating. A photosensitive film(14) is adhered to a polyimide(10), and the photosensitive film is developed with exposure and a circuit is patterned by using a photolithography. The surface of selected patterned polyimide patterned is selectively modified, and a metal seed layer(16) is formed on the surface modified polyimide by using an electroless plating. A copper layer is formed on the metal seed layer by using the electroplating, and the photosensitive film is eliminated, and the flexible conductive polyimide substrate is washed.
