Abstract
The present invention provides a communication device that can reduce a housing of an electronic device in size and thickness when the communication device is built in the electronic device. The communication device includes: an antenna coil (11a) arranged on an outer peripheral portion (134) of a housing (131) surface facing a reader/writer (120) of a mobile phone (130); a magnetic sheet (13) that attracts a magnetic field transmitted from the reader/writer (120) to the antenna coil (11a); and a communication processing unit (12) that is driven by a current flowing in the antenna coil (11a) and performs communication with the reader/writer (120), wherein the magnetic sheet (13) is arranged on the reader/writer (120) side of the antenna coil (11a) at a center portion (132a), and the antenna coil (11a) is arranged on the reader/writer (120) side on an outer periphery (130d) side.
