<P>PROBLEM TO BE SOLVED: To provide electroconductive ink forming a conductive circuit excellent in dimensional stability, at low temperature and within a short time, realizing sufficiently low volume resistivity of thin films, and excellent in ink stability and fluidity, and to provide noncontact type media having a conductive circuit formed by ordinal printing methods, and contributing to mass production, cost down and energy saving. <P>SOLUTION: The electroconductive ink comprises a conductive material and a binder component, wherein chlorinated polyolefin resin is used as the binder component and a flaky metallic powder having 0.5-2.5 m<SP>2</SP>/g BET specific surface area and 2-5 g/cm<SP>3</SP>tap density is used as the conductive material. And the noncontact type media comprises a conductive circuit formed on a substrate by using the electroconductive ink and an IC chip mounted in a state conducted to the conductive circuit. <P>COPYRIGHT: (C)2008,JPO&INPIT |
