Abstract
A near-field communication device includes a communication antenna for near-field communication formed along a plane, an interface circuit connected to the communication antenna for making a signal of the near-field communication pass through the interface circuit, a wireless communication IC connected to the interface circuit for processing the signal of the near-field communication, a power reception coil arranged along the plane to surround the communication antenna, a resonant capacitor constituting, together with the power reception coil, a power reception resonant circuit, and a rectifying and smoothing circuit connected to the power reception resonant circuit. The power reception resonant circuit resonates at a frequency of the near-field communication, and magnetic flux generated in the vicinity of the power reception coil by a resonant current flowing through the power reception resonant circuit interlinks with the communication antenna.
