Abstract
A communication device that, when incorporated in an electronic device, can reduce the size and the thickness of a housing of the electronic device while maintaining communication characteristics. The communication device includes an antenna coil that is arranged on a peripheral part of a housing surface facing a reader-writer of a mobile phone, a magnetic sheet that attracts the magnetic filed transmitted from the reader-writer to the antenna coil, and a communication processing unit that is driven by a current flowing through the antenna coil and communicates with the reader-writer. The magnetic sheet is arranged to be closer to reader-writer than the antenna coil in the central part, and the antenna coil is arranged to be closer to the reader-writer on the outer periphery side, and at least a part of the conductive line of the antenna coil is superimposed in a direction orthogonal to a circuit board.
