<P>PROBLEM TO BE SOLVED: To provide a contactless data receiver and transmitter which suppresses the increase of a thickness in the contactless data receiver and transmitter, has excellent flexibility, and can be used by inducing electromotive force which fully exceeds the operation electromotive force of an IC chip even when contacting an article containing at least metal. <P>SOLUTION: The contactless data receiver and transmitter 10 comprises: a base material 11; and an inlet 14 which is arranged on one surface 11a of the base material, having an antenna 12 and an IC chip 13 which are mutually connected. The antenna 12 has a coil shape via the IC chip 13. A magnetic material layer 15 is arranged on the base material 11 to cover the antenna 12 and the IC chip 13, excluding both the end parts 12c, 12c of the antenna and its neighbor area. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
