Abstract:
1. A method for forming a conductor, comprising: a first printing step of printing a contour part of the conductor with a first printing ink such that the contour part extends along an outer periphery of the conductor; a drying step of drying the printed contour part; and a second printing step of printing a remaining part of the conductor with a second printing ink, the second printing ink containing a conductive material and having a surface tension lower than or equal to a surface tension of the first printing ink, said method further comprising, before the drying step, printing an aggregation preventing part inside the contour part of the conductor, wherein the aggregation preventing part is dried simultaneously with the contour part of the conductor in the drying step; and wherein the second printing ink is printed on the remaining part of the conductor other than the contour part and the aggregation preventing part in the second printing step.
