A conductive ink for forming a fine conductive pattern on a substrate by the letterpress reverse printing method. In particular, the pattern can be stably formed without the occurrence of transfer failures, and excellent conductivity can be imparted to the conductive ink by low-temperature burning. The conductive ink comprises conductive particles having a volume-average particle diameter (Mv) of 10-700 nm, a release agent, a surface energy regulator, and a solvent ingredient as essential ingredients, the solvent ingredient being a mixture of a solvent having a surface energy as measured at 25°C of 27 mN/m or higher (high-surface-energy solvent) and a volatile solvent having a boiling point as measured at atmospheric pressure of 100°C or lower (low-boiling solvent). The ink has a surface energy as measured at 25°C of 10-21 mN/m and contains substantially no binder ingredient. |
