To provide a communication method for a wireless remote control group that utilizes each wireless remote controller for a relaying device so as to realize stable communication in the case of communication between the wireless remote controller group distributingly arranged.

The wireless remote controllers distributingly arranged try to make inter-communication at a prescribed time. On the basis of the communication result, a list of directly communicating wireless remote controller group is prepared for each of the wireless remote controllers. Each wireless remote controller requests wireless remote controllers included in the directly communicative wireless remote controller group list to transmit the directly communicative wireless remote controller group list, collects chains of the directly communicating wireless remote controller group lists and creates a communication route group list by using the chained list groups. Then each wireless remote controller makes communication with a target wireless remote controller through the relay along communication routes selected by the communication route group lists.
