An electronic endoscope system includes a scope section, an in vitro apparatus which is installed outside a body, and a connecting cord section which connects the scope section and the in vitro apparatus. Each of the in vitro apparatus and the connecting cord section includes pads which are structured to be air tight and water tight, and connecting sections for bringing close upon facing each of the pads. Furthermore, for performing a communication of a signal between a pair of pads facing each other, the electronic endoscope system includes a first modulating unit which applies a voltage on one of the pads upon modulating the signal, and a demodulating unit which demodulates the signal from a change in an electric potential of the other pad. |
