PROBLEM TO BE SOLVED: To provide a technology capable of attaining a contact even when a public communication means such as a mobile phone is not available because of occurrence of emergency or crowded traffic. SOLUTION: Adhoc multihop communication among a plurality of terminals automatically forms an adhoc network communication path while selecting a relay terminal 21 on the basis of whether or not a second terminal 22 being a connection destination of a first terminal 20 being a connection source has connection destination information not stored in a first terminal 20. In this case, each terminal collects connection destination information stored by each terminal in advance capable of adhoc communication, and establishes a communication path via a selected terminal even when the relay terminal desirably acquirable of information is selected and the path is deviated from the shortest path. When the first terminal 21 acquires information from the other terminal (22), the first terminal 21 attaches identification information by each terminal to transmission data of the adhoc communication to sequentially acquire connection destination information in each terminal while relaying terminals on the way of communication without the need for acquisition beforehand and automatically attaches the connection destination information to the transmission data.
