To provide a data communication device capable of performing a stable human body communication by bringing the human body into contact with electrodes or proximities thereof without requiring user's attention when the data communication device held by the user is in the process of the human body communication. A transceiver electrode 103 and a reference electrode 104 are formed on concave portions 102 formed at positions where the user's fingers can be naturally brought into contact with the concave portions 102 when a data communication device 10 is held by one of the user's hands, such that the surfaces of the electrodes have a height slightly lower than those of the lateral portions of the housing 101. The transceiver electrode 103 and the reference electrode 104 are electrically connected, via a lead line 106, to a data communication unit 105 accommodated in the housing 101 and having a function of transmitting and receiving data. By bringing a communication party holding the data communication device 10 into contact with a human body and thus forming a closed circuit, data can be transmitted or received to and from the data communication unit 105 via the human body.
