The present invention provides a conductive ink for forming a fine conductive pattern on a substrate by letterpress reverse printing. In particular, the conductive ink enables the pattern to be formed stably without the occurrence of transfer failures and is able to impart superior conductivity by low-temperature baking. The conductive ink, which contains substantially no binder component, comprises as essential components thereof conductive particles having a volume average particle diameter (Mv) of 10 to 700 nm, a release agent, a surface energy regulator and a solvent component, the solvent component being a mixture of a solvent having a surface energy at 25°C of 27 mN/m or more (high surface energy solvent) and a volatile solvent having a boiling point at atmospheric pressure of 100°C or lower (low boiling point solvent), and the surface energy of the ink at 25°C is 10 to 21 mN/m. |
