An inexpensive, safe carbon dioxide gas exposure respiration training tool having a simple structure of hollow tubular body, with which carbon dioxide gas exposure training of the respiratory organs can be carried out by attaching the tool and simply breathing air ordinarily while sleeping, bodily conditions such as those of respiratory organs and the circulatory system can be improved, and health can be promoted. The carbon dioxide gas exposure respiration training tool comprises a mask section (2) having a fixing tool (5) at the end and a respiration opening (21) opening to the central part, an air intake vent (3) communicating with the respiration opening (21) in proximity thereto, and a hollow tube (1) having an inner cavity in the form of a communicating channel communicating with the vent (3), introducing expiration from the respiration opening (21) side and, while allowing stagnation thereof freely, discharging the expiration into the atmosphere from a discharge opening (4) opening to the opposite side end. Mouth and nose are covered by the mask section (2) and the hollow tube (1) is attached below the face or the periphery of the neck.
