<P>PROBLEM TO BE SOLVED: To provide a non-contact data carrier which is applied with processing of a through-hole or the like for a mounting hole such that a work part causes no adverse effect on an IC or the like, and even if a metallic chain is passed through the bored through-hole for the mounting hole, a resonance point is not deviated, permitting communication favorably, and to incorporate a function as an accessory to the data carrier by way of printing a desired character, picture or the like on the front/back face of the data carrier, or the like. <P>SOLUTION: In the non-contact data carrier, an antenna circuit member of structure retaining an antenna coil and an IC chip with a resin base material and heat fusion bond resin base materials placed on the front and back of the member are put together by heat fusion bonding, and the antenna circuit member is embedded in between the base materials. The work part of the mounting hole or the like is disposed on a periphery of an antenna coil with which the heat fusion bond resin base materials contact on the front and back sides. <P>COPYRIGHT: (C)2004,JPO |
