[Object] To provide a conductive ink composition which allows formation of a high resolution conductive pattern, and which can provide a high conductivity pattern by firing at a lower temperature and in a shorter time. [Solution] The aforementioned object is achieved by including a conductive filler, an epoxy compound, a blocked polyisocyanate in which a blocking agent is an active methylene compound and/or a pyrazole compound, a reaction catalyst for the blocked polyisocyanate, and an organic solvent as essential components. A conductive ink composition of the present invention can be fired at a lower temperature and in a shorter time and allows printing of a higher resolution conductive pattern.

Provided are a gravure offset printing method, a gravure offset printing apparatus, and a gravure plate that allow a fine wiring pattern to be accurately printed on the material to be printed. A gravure offset printing method executed by a gravure offset printing apparatus includes a step of filling a groove on a gravure plate with a printing paste, a step of offsetting the printing paste from the groove on the gravure plate to the blanket, and a step of transferring the printing paste from the blanket to a substrate. The groove on the gravure plate includes a region having a width of 100 to 700 &#x3bc;m in a direction perpendicular to a print direction. The region has a leading end tapered forward in the print direction and a trailing end split into a pair of branches by a notch tapered forward in the print direction.
