A communication device capable of transmitting a signal by two-dimensional diffusive signal transmission technology includes: a signal layer in which the signal is transmitted; a plurality of communication chips which are connected to the signal layer to transmit the signal by the two-dimensional diffusive signal transmission technology; a power supply layer which supplies electric power to each of the communication chips; a ground layer which is electrically connected to each of the communication chips as ground for the electric power; and an attenuation layer which is placed between the signal layer and the power supply layer, attenuates electric current that can flow between the signal layer and the power supply layer, and pulls up electric potential of the signal layer toward that of the power supply layer.
