PROBLEM TO BE SOLVED: To prevent wrong pull-out of a communication cable, by indicating presence or absence of communication information in the communication cable.SOLUTION: A communication visualization system 10 includes a wireless power feeding device 11, a communication detector 12, and a determination device 13. The wireless power feeding device 11 radiates sine waves. The communication detector 12 converts the sine waves into a DC voltage, as the drive power of the communication detector 12, and outputs a detection signal by detecting that a LAN cable 60, connected with an information communication apparatus 61, is during information communication. The determination device 13 identifies the LAN cable 60 during information communication, on the basis of a detection signal outputted from the communication detector 12, and indicates presence or absence of information communication of the LAN cable 60. |
