PROBLEM TO BE SOLVED: To provide a method for easily forming a region with conductivity and high wettability without a step for removing a photocatalytic reaction layer, which is formed over a conductive layer. SOLUTION: The photocatalytic reaction layer is formed over a photocatalytic conductive layer, and the photocatalytic conductive layer is irradiated with ultraviolet light to form a region with conductivity and higher wettability than the photocatalytic reaction layer on a surface of the photocatalytic conductive layer which is irradiated with ultraviolet light, wherein as the photocatalytic conductive layer, a layer having a photocatalytic property of which resistivity is≤1×10<SP>-2</SP>Ωcm can be used.
