Patent ID: 7278725

Claim:
A method for forming a predetermined wiring pattern on a base board by ejecting a liquid drop from a liquid drop ejecting head onto a plurality of unit areas formed on the base board, the liquid drop being made from conductive particles dispersed in a dispersion medium, the method comprising: forming a first pattern by a first nozzle group formed in the liquid drop ejecting head; forming a second pattern by a second nozzle group formed in the liquid drop ejecting head which is different from the first nozzle group; and dehydrating the ejected liquid drop, wherein the liquid drop is ejected to the unit area by the first nozzle group, and the liquid drop is ejected to a border section between unit areas by the second nozzle group, and wherein the first pattern corresponds to a linear line pattern expanding in an X-axis direction and corresponds to unit areas of an inclining line pattern connected to the linear line pattern and expanding in an inclining direction to the expanding direction of the linear pattern, the second pattern corresponding to the border section between the unit areas of the inclining line pattern, so that the first and second pattern are formed on the base board.
