る。SUMMARY OF THE INVENTION Such a non-contact type I
The C card has the same size and thickness as the CD card (ISO standard 84.10) in consideration of carrying around and future multifunctionalization.
5 mm x 54.0 mm x 0.8 mm) is required.
Depending on the frequency used, it would not be possible to form within the dimensions of a normal half-wavelength antenna,
Further, a microstrip antenna or the like having a ground conductor on the back surface has various problems, such as an extremely narrow band characteristic due to a reduction in thickness. SUMMARY OF THE INVENTION An object of the present invention is to provide an IC card having an antenna which is excellent in miniaturization, thickness reduction, broadband, and inexpensive.

端な狭帯化が生じにくい。As shown in FIG. 1, an IC card according to the present invention has a conductor D1 formed on a thin plastic film and a U-shaped conductor formed so as to surround the conductor D1. The antenna is constituted by the ground conductor D2. This U-shaped antenna is obtained by making both ends of a normal slot antenna electrically open and deforming it into a U-shape, whereby the length L1 of the antenna is １ ／ wavelength of the operating frequency. Since the ground conductor is formed not on the back but on the same plane as the conductor, extremely narrow band is unlikely to occur even in a thin shape such as an IC card.

The ground conductor D2 may be formed using a so-called conductive ink. As a result, not only the cost can be reduced as compared with a general etching method, but also the band width can be widened by increasing the resistance of the conductor.
