A radio terminal 1 has a self-terminal information storing section 4 for storing terminal information of its own, an other terminal information storing section 3 for temporarily storing terminal information which is sent from other radio terminals, and a master determining section 2 for determining a radio terminal appropriate for being a tentative master, based on the stored terminal information. This master determining section 2 determines the tentative master based on the specified information of the terminal information such as transmission power, battery information and network address information. Since, if a user selects an appropriate radio terminal and starts the construction of a temporary network, the radio terminal acquires terminal information of all other terminals and determined an optimum tentative master, the network is then constructed while being the determined tentative master as a center, and communication can be conducted.
