<P>PROBLEM TO BE SOLVED: To reduce only a noise current without reducing a signal current even when a CMC is used. <P>SOLUTION: An electric field communication system, or the one which makes use of a common mode choke coil 5, comprises an impedance adjustment unit 10 which adjusts the impedance of a path R2; a transmission unit 2 which, only when the user keeps touching an electrode P3, transmits a data signal by using a path which has had its impedance adjusted by the impedance adjustment unit 10; and a reception unit 3 which receives the data signal transmitted by the transmission unit 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
