PROBLEM TO BE SOLVED: To allow each radio station to autonomously construct a start type multi-hop radio network by finding the optimal destination of connection (high order connection destination radio station). SOLUTION: The number of hop information obtaining means for each radio station obtains the number of hop information from a connectable radio station, and when direct connection to a base station is available, a high order connection destination radio station selecting means selects the base station as a high order connection destination radio station. In other cases, selects one connectable radio station whose number of hops obtained from the number of hop information can be made the minimum as the high order connection destination radio station from among the connectable radio stations. Then, a signal transferring means transfers a transmission signal or a signal received from a slave radio station to the high order connection destination radio station, or when direct connection to the base station is available, transfers the signal to the base station.
