<P>PROBLEM TO BE SOLVED: To provide a transceiver capable of being miniaturized by providing a switch circuit. Ž<P>SOLUTION: In the transceiver 1, when a switching control circuit 16 determines that a power switch SW is turned on, a display control part 13 makes information stored in a memory 14 be displayed on a display device 12 by supplying signals to an electrode P through a switch SW1 which is on. Then, the switching control circuit 16 turns off the switch SW1 of the switch circuit 15 and turns on a switch SW2. A communication circuit 11 applies a voltage of a waveform based on information to be transmitted through the switch SW2 which is on to an electrode P. The electrode P is capacitively coupled to the electric field transmission medium and an electric field is generated between the electric field transmission medium and the ground. Part of the electric field passes through the other transceiver, and thus the voltage of the same waveform is applied to a similar electrode provided in the other transceiver. The other transceiver reproduces the information by the waveform of the voltage. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
