ABSTRACT:
An IC tag and an IC card are provided to achieve reduction in size, improvement on workability and the yield rate when manufacturing, reduction of manufacturing cost, etc., The IC tag of this invention is formed for transmitting information in non-contact manner, and two pieces of antenna circuits2are folded and superposed on each other therebetween. One of the two pieces of antenna circuits2is a mounted circuit2A on which an IC chip6is not mounted, and the other is an opened circuit2B on which on IC chip6is mounted. On one surface of the antenna circuit2is provided a surface printing material10on which visible information is printed. On the other surface of the antenna circuit2is provided an adhesive member, so that the antenna circuit2can be stuck with each other by folding a circuit support portion4.
