  • Publication number: 20100078487
    Abstract: A method of manufacturing RFID tags. A base sheet member is formed by fixedly attaching unit base substrates to a belt-like first sheet member at predetermined space intervals. Each unit base substrate is formed with an antenna pattern and has a non-contact communication-type IC chip mounted thereon. An upper-layer sheet member is formed by arranging reinforcing members between elastic, belt-like second and third sheet members, and is laminated on a surface of the first sheet member toward the unit base substrates such that each IC chip and each reinforcing member overlap each other in plan view. Regions each containing one unit base substrate are sequentially cut out from a laminate of the upper-layer sheet member and the base sheet member, thereby making RFID units.
