ABSTRACT:
It is an object of the present invention to provide a conductive ink which enables to form a circuit or the like having excellent adhesion to a substrate and to form a conductor having high film density and low electric resistance. In order to attain the object, a conductive ink comprising metal powder or metal oxide powder dispersed in a dispersion medium, which is characterized in that the dispersion medium contains a metal salt or a metal oxide as a film density improver for increasing film density of a conductor formed by using the conductive ink is adopted. A main solvent constituting the dispersion medium is selected from 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 deg. C. or less at normal pressure.
