PROBLEM TO BE SOLVED: To provide a human body transmission system which reports the consumption of the batterly of a first data communication unit worn on a human body, without increasing the power consumption or the size of this unit. SOLUTION: The communication system has a first data communication unit 10 having electrodes contacted to a human body, and a second data communication unit 30 having contact electrodes contactable with the human body for performing a data communication with the first data communication unit 10. The first data communication unit 10 has a means 70 for detecting the remaining capacity of a batterly 14 for operating itself, and a means for transmitting batterly remaining capacity information D1 obtained therefrom. The second data communication unit 30 has a means for receiving the batterly remaining capacity information D1, and a means 60 for indicating the remaining capacity condition of the batterly, based on the received batterly remaining capacity information D1.
