Abstract: A conductive ink composition according to the present disclosure is a conductive ink composition that can be printed on a substrate, and this conductive ink composition includes a first metal precursor of which a first metal ion may be reduced to a first metal by heat, to form a conductive coating film on the substrate, and a photothermal material for absorbing light energy such as laser and discharges the heat to surroundings, to raise the surrounding temperature to a temperature not below the temperature at which the first metal ion may be reduced, and therefore the present disclosure enables to easily form a coating film that includes a conductive first metal regarding a disconnected point during a process of forming a fine pattern, thereby enabling efficient repair.
