<P>PROBLEM TO BE SOLVED: To provide a communication system making safety of a diver most preferential in an information communication system for a diver. Ž<P>SOLUTION: The communication system is constituted by a communication machine 40a mounted to an underwater respiration device 50a and a diving computer 1. The communication machine transmits measurement data from a sensor 44a and respiration monitoring data including a communication identifier and a device identifier of the respiration device and describes the communication machine identifier in the respiration monitoring data by a complement when abnormality is present in the measurement data. The diving computer 1 memorizes the communication machine identifier and the device identifier, outputs information of the content of the measurement data included in the received respiration device monitoring data, and outputs warning information when the communication machine identifier of the respiration device monitoring data is described by the complement.
