(57) [Summary] [Problem] When forming a conductive pattern by an additive method, if a reactive layer remains on a substrate, the stability of the obtained conductive pattern substrate is impaired. It is an object of the present invention to solve the problem. SOLUTION: A photocatalyst substrate in which a photocatalytic layer 6 is laminated on a second substrate 5 on a wettable variable substrate 1 in which a wettable layer 3 is laminated on a first substrate 2 By laminating No. 4 and pattern exposure, a wettability pattern was formed, and a conductive coating liquid or the like was adhered thereto, whereby a conductive pattern base material containing no photocatalyst could be manufactured. |
