Abstract:
Near field communication device has a configuration in which at least a part of coil of coil element is covered with cover at a portion opposite to substrate and a part of cover is fixed to substrate directly or indirectly. Therefore, even when near field communication device is mounted to one of various electronic apparatuses in a vicinity of display unit outer peripheral frame made of metal, a large change in impedance or a large reduction in magnetic field strength can be prevented. As a result, a reduction in receiving sensitivity can be suppressed.
