PROBLEM TO BE SOLVED: To obtain cards having circuits or the like formed by a conductive ink capable of conveniently handling by obtaining a conductive ink which is tough against to folding while having solvent vaporizing type advantages such as short curing time and low-resistance. SOLUTION: This ink includes 0.2-5 wt.% (solid content) of a tacky resin (e.g. polyvinylether or polybutadiene) having <=0 deg.C of glass transition point (Tg) in a solvent vaporizing type conductive ink.
