Abstract: Coil units including windings are disposed on opposite sides across a virtual center line that is substantially perpendicular to a direction of positional displacement of a portable electronic apparatus that is to be disposed close to a reader/writer. The windings are connected in series through a conductor such that winding directions of the windings are the same. A difference in the communication performance between a case where the portable electronic apparatus is brought closer to a central portion of the reader/writer and a case where the portable electronic apparatus is brought closer to a position that is deviated from the central portion of the reader/writer can be reduced. In particular, even in a case where the portable electronic apparatus is brought closer to a peripheral portion of the reader/writer, a predetermined maximum possible communication range can be ensured.
