An object of the present invention is to provide a conductive ink which is excellent in adhesiveness between a circuit and a substrate formed using the conductive ink and has a high film density and low electrical resistance. In order to achieve this object, a metal salt as a film density improving agent for improving the film density of a conductor formed by dispersing a metal powder or a metal oxide powder in a dispersion medium using the conductive ink in the dispersion medium. Or a conductive ink characterized by containing a metal oxide. As the main solvent constituting the dispersion medium, one or a combination of two or more selected from the group consisting of water, alcohols, glycols and saturated hydrocarbons having a boiling point of 300 ° C. or lower at normal pressure is adopted. . |
