PROBLEM TO BE SOLVED: To compose an antenna of a conductor pattern and to thin entire configuration or to attain improvement in production workability even when using a medium wave as a radio wave. SOLUTION: Concerning the configuration of this remote ID tag, pattern coils 14-19 are provided on both the sides of planar parts 11-13 on a flexible printed circuit board 6 and insulating layers are provided on both the sides of the flexible printed circuit board 6 for covering the pattern coils 14-19 so that when the flexible printed circuit board 6 is folded, the winding directions of two adjacent pattern coils with the flexible printed circuit board 6 or insulating layer inbetween among the pattern coils 14-19 can be inverted. Then, the respective terminal parts of the pattern coils 14-19 are connected so as to constitute one coil, for which the pattern coils 14-19 are sequentially wounded in the same direction, and the antenna is composed of one coil as mentioned above. |
