In a wireless communication terminal (10), the other terminal existence confirmation section (11) broadcasts a confirmation message at fixed intervals and receives a response message. The topology information management section (12) computes the topology of the whole network to which the wireless communication terminal itself belongs, on the basis of the topology information on the network received at fixed intervals from other terminals. The path management section (13) derives an optimum path to the terminal of the transmission destination. The QoS information collection section (14) issuesa communication start request instruction and, when a QoS information collect request instruction has been issued, unicasts a QoS request packet on the path and receives a reply QoS request packet. The judgment section (15) adopts the path as the communication path when QoS information satisfies a predetermined quality standard.
