PROBLEM TO BE SOLVED: To ensure connection of a fluid passage and send/receive a signal between connecters. SOLUTION: In connecting portions of a first fluid connector 10 and a second fluid connector 30, electromagnetic coils 15 are arranged respectively and a voltage is applied to them. The connectors are attracted and coupled to each other by using an electromagnetic force generated in the electromagnetic coils 15. On the voltage to be applied to the electromagnetic coils 15, fluctuation voltage is superposed depending on a signal to be sent, whereby the signal is transmitted by using an electromagnetic induction generated between the coils 15.
