<p><P>PROBLEM TO BE SOLVED: To provide an IC tag which never causes malfunction in reaction to a metal detector even when it is used for an article needing inspection by the metal detector such as a linen article, and can sufficiently perform contactless information communication with an external communication device. <P>SOLUTION: The IC tag for storing electronic information and performing information communication with an external information communication device in no contact comprises an electronic circuit part 32, an antenna part 34, and a protective outer shell part 20. The electronic circuit part 32 is composed of a bare IC chip having a projection area of 0.1-2 mm<SP>2</SP>. The antenna part 34 is composed of a winding antenna having an outer circumferential area of 30-1,200 mm<SP>2</SP>, which is wound on a nonmagnetic conductive wire lod 10-100μm in diameter, both ends of the antenna being directly bonded to the bare IC chip of the electronic circuit part 32. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
