PROBLEM TO BE SOLVED: To provide an electroconductive ink composition that can produce an electroconductive member having sufficient electroconductivity under a simple atmosphere such as air or the like and under a drying condition at a temperature lower than the conventional one even when the composition uses a micro-sized copper particle.SOLUTION: The electroconductive ink composition contains (A) an oxycarboxylic acid, (B) a nitrogen-containing compound, (C) a copper particle and (D) a dispersion medium. The nitrogen-containing compound (B) is at least one kind of compound selected from the group consisting of a compound having a urea bond, guanidine and a derivative thereof, a guanidine salt, a heterocyclic 5-membered ring compound including two nitrogen atoms as a heteroatom, 1H-triazole and a derivative thereof, a hydrazine compound, a nitrosamine compound, a compound having a nitrile group, melamine and a derivative thereof, and an ammonium salt.SELECTED DRAWING: None |
