1. A communication device comprising:
- an antenna that generates a magnetic field, and communicates with a wireless device that generates a magnetic field during communication;
a sensor that detects magnetic field strength by receiving the magnetic field of the antenna and the magnetic field of the wireless device; and
a notification component that notifies a positional offset between the antenna and the wireless device based on output signal indicative of the magnetic field strength detected by the sensor,the sensor being arranged with respect to the antenna with an effect of the magnetic field generated by the antenna on the output signal being suppressed.

Abstract
A communication device includes a sensor, an antenna, and a notification component. The sensor is configured to detect magnetic field strength. The antenna is configured to generate a magnetic field. The antenna is further configured to communicate with a wireless device that is configured to generate a magnetic field during communication. The notification component is configured to notify a positional offset between the antenna and the wireless device based on output signal indicative of the magnetic field strength. The sensor is arranged with respect to the antenna such that an effect of the magnetic field generated by the antenna on the output signal is suppressed.
