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.
Claims12
A near field communication device comprising:
- a substrate;
- and
- a coil element mounted on a surface of the substrate, and including a core and a coil wound around an outer periphery of the core,
- wherein at least a part of the coil is covered with a cover at a portion opposite to the substrate, and a part of the cover is fixed to the substrate directly or indirectly.
