Provided is a pressurized carbon dioxide bathing apparatus for bringing carbon dioxide into contact with skin of a living body by a predetermined pressure value or more using compressed air, and thereby enabling carbon dioxide to be absorbed efficiently from the skin, and the pressurized carbon dioxide bathing apparatus is comprised of a carbon dioxide supply means 1 for supplying a mixed gas of carbon dioxide and water vapor containing one or a plurality of chemical agents, a compressed air supply means 2, and a cover suit 3 of a two-layer structure having an enclosed layer 4 that is connected to the carbon dioxide supply means 1 via a connector 6 to confine the mixed gas supplied from the carbon dioxide supply means 1 so as to bring the mixed gas into direct contact with skin of the human body and an enclosed layer 5 that is connected to the compressed air supply means 2 via a connector 7 to confine compressed air supplied from the compressed air supply means 2, where the carbon dioxide is brought into contact with skin of the human body with a predetermined pressure value or more by the compressed air.
