In a via-human-body information transmission system, there is made so as to be capable of more stably transmitting a signal. An electrode ( 104 ) of a transmitter-receiver ( 102 ) contacting with or capacitance-connected to a human body ( 101 ) and an electrode ( 108 ) of a receiver ( 106 ) contacting with or capacitance-connected to the human body ( 101 ) are electrically connected through the human body ( 101 ) (mainly, a chest part and a left arm). An electrode ( 105 ) of the transmitter-receiver ( 102 ) contacting with or capacitance-connected to the human body ( 101 ) and an electrode ( 109 ), of the receiver ( 106 ), having been disposed while being directed to an outside of the human body ( 101 ) are electrically connected by a capacitance connection. A communication between the transmitter-receiver ( 102 ) and the receiver ( 106 ) is performed through a path passing the electrodes ( 104, 105, 108, 109 ) and the human body ( 101 ) and a path by the capacitance connection.
