<P>PROBLEM TO BE SOLVED: To provide a communication device with which the size and the thickness of a housing of an electronic device can be reduced when the communication device is incorporated in the electronic device, while maintaining communication characteristics. <P>SOLUTION: The communication device comprise an antenna coil 11a which is disposed on an outer circumferential portion 134 of a surface of a housing 131 that faces a reader writer 120 in a cellular phone 130, a magnetic sheet 13 which leads to the antenna coil 11a a magnetic field transmitted from the reader writer 120, and a communication processing section 12 which is driven by a current that flows in the antenna coil 11a and communicates with the reader writer 120. The magnetic sheet 13 is disposed such that the magnetic sheet 13 is closer to the reader writer 120 side than the antenna coil 11a on a center portion 132a, and such that the antenna coil 11a is disposed on the reader writer 120 side on an outer periphery 130d side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
