To provide a mobile phone in which a display unit is movable to an operation unit, which is commonly used for electric field communication, including a transceiver performing electric field communication and a computer controlling electric field communication, eliminates the risk of touching a signal electrode for electric field communication and a ground electrode at the same time when a user uses it in a hand in a usual usage mode of the mobile phone, and sufficiently demonstrates the electric field communication performance.
The mobile phone 11 is characterized in that the mobile phone 11 includes the transceiver 117 performing electric field communication and the computer 118 controlling electric field communication, the display unit 111 is a movable unit to slide or rotate with respect to the operation unit 110, and the signal electrode 113 for electric field communication and the ground electrode 114 are installed in the positions electrically facing each other on a surface or inside of the display unit for connection with the transceiver.
