PURPOSE: A transmitting/receiving apparatus and a communications system with the transmitting/receiving apparatus are provided to improve the reception efficiency when receiving an information signal. CONSTITUTION: A transmission and reception electrode(11) contacts or is coupled to a transmission medium. A reception system(12) contacts the transmission and reception electrode, and a transmission system(13) contacts the transmission and reception electrode. In the signal transmission, the state of the reception system viewed from the transmission and reception electrode is in an open state. The impedance viewed from the transmission and reception electrode to the transmission system is matched with specific impedance.
