ANTENNA APPARATUS AND COMMUNICATION APPARATUS

摘要

Provided is a communication apparatus, with which, while maintaining communication characteristics, a housing of an electronic apparatus can be reduced in size and thickness when the communication apparatus is assembled to the electronic apparatus. The communication apparatus is provided with: an antenna substrate (11) having an antenna coil (11a) formed thereon, said antenna coil to be inductively coupled with a reader writer (120); and a magnetic sheet (13), which draws a magnetic field to the antenna coil (11a), said magnetic field having been transmitted from the reader writer (120). In the direction in which the magnetic sheet (13) is inserted into a center portion (11c) of the antenna coil (11a) formed on the antenna substrate (11), both the end portions (13a, 13b) of the magnetic sheet (13) are positioned further toward the center portion (11c) than both the end portions (11d, 11e) of the antenna coil (11a).
