PROBLEM TO BE SOLVED: To provide a gas supplying device for respiration with the high safety and reliability, which has the possibility of ignition by an accident or the like and is improve in a safety by suppressing ignitability. SOLUTION: This gas supplying device for respiration has a gas generating means for respiration which separates oxygen from air and supplies the oxygen to the user and a casing which internally has this gas generating means for respiration. The circumferential part of the gas generating means for respiration within the casing is provided with a gaseous nitrogen packing means which packs the high-density gaseous nitrogen after the separation of the oxygen from the air into the generating means.
