PROBLEM TO BE SOLVED: To provide a communication device for attaining advancement in top secret by intricately changing the frequency of a radio wave receiving and transmitting device to two or more classifications. SOLUTION: The communication device includes a signal distribution integrated regulator 1 which distributes and saves transmission data at two or more classifications of the transmission frequencies; a radio wave receiving and transmitting device 1 which distributes and transmits the transmission data for every set transmission frequencies; a radio wave receiving and transmitting device 2 which receives the transmission data transmitted for every transmission frequency; a signal distribution integrated regulator 2 which integrates the transmitted data for every received transmitting frequencies and restores to the original transmitting data before the distribution; a signal distribution integrated regulator 2 to the signal distribution integrated regulator 1; and a computer or a control unit 2 which transmits the change instructions of the transmitting frequencies through the signal distribution integrated regulator 2, and the radio wave receiving and transmitting device 1, to the signal distribution integrated regulator 1. The signal distribution integrated regulators 1 and 2, respectively perform the setting change of the switching of the transmitting frequencies of the radio wave receiving and transmitting devices 1 and 2.
