PROBLEM TO BE SOLVED: To provide a wiring substrate manufacturing method which can form wiring including &pgr;-conjugated system conductive polymer on a surface of an insulating base material simply and with high definition, and which can achieve high conductivity and transparency.SOLUTION: A wiring substrate manufacturing method of a present embodiment comprises: a conductive polymer coated film formation process of forming a conductive polymer coated film by coating at least on one surface of an insulating base material, a conductive polymer dispersion liquid which includes &pgr;-conjugated system conductive polymer, polyanion and a dispersion media; a resist film formation process of forming a resist film on a surface of the conductive polymer coated film by printing a resist paste which includes a resist film forming resin and a resist film forming medium by screen printing and in a predetermined pattern; an inactivation process of processing the conductive polymer coated film which is not coated by the resist film by an etchant which inactivates the conductive polymer coated film; and a resist film removal process of dissolving or swelling the resist film by a solvent for removal after the inactivation process to remove the resist film. |
