<p><P>PROBLEM TO BE SOLVED: To provide an electrically conductive ink which prevents deforming or cracking of hardened materials forming a land portion or a jumper portion, stabilizes electrical characteristics suppressing an increase in electrical resistance, and maintains a stable adhesive bonding, when the land portion is heated or pressed for installing an integrated circuit chip on it or the jumper portion is heated or pressed for forming it, and to provide a radio frequency identification medium using the electrically conductive ink. <P>SOLUTION: The electrically conductive ink which comprises a vehicle consisting mainly of thermosetting resin and an electrically conductive material of 55 to 70 wt.% for a sum of the vehicle and the electrically conductive material, is used. The radio frequency identification medium is manufactured by forming an electrically conductive connecting portion on a prescribed portion of a base plate using the electrically conductive ink. <P>COPYRIGHT: (C)2004,JPO</p> |
