Abstract: Disclosed is an active energy ray-curable conductive ink containing a conductive substance and a binder component, which is characterized in that the binder component contains a chlorinated polyester and an active energy ray-polymerizable compound. This active energy ray-curable conductive ink has good fluidity and enables to obtain a conductive circuit with low resistance after curing. Also disclosed are a method for forming a conductive circuit by printing this conductive ink on a substrate, and non-contact media comprising an IC chip mounted in a state electrically connected with the conductive circuit. The conductive substance is preferably a flake powder having a BET specific surface area of 0.1-0.4 m2/g and an aspect ratio of not less than 3.
