This invention relates to the conductive ink composition which disperse | distributed the solid substance which coat | covers the surface of metal fine particles containing the alloy containing at least a noble metal with the protective colloid containing 2 or more types of organic compounds in the organic solvent. As said protective colloid, the protective colloid obtained from the raw material containing (A) amines and (B) carboxylic acid is used, for example. By apply | coating and baking the said electroconductive ink composition, particle growth is suppressed, the metal film which is excellent in the surface smoothness and adhesiveness with the application target can be obtained more than before.n n n n Conductive ink composition, reflective member, circuit board, electronic device |
