An ink composition for photonic sintering and a method or producing the ink composition, the ink composition includes: metal nanoparticles comprising a first metal satisfying interaction formula 1; an organic non-aqueous binder; and a non-aqueous solvent. Interaction formula 1 is A1/A2≤0.2, where A1/A2 is a ratio, in the x-ray photoelectron spectrum on the surface of the first metal, in which first metal 2p3/2 peak area of the oxide of the first metal (A1) is divided by first metal 2p3/2 peak area of the first metal (A2).
