The present invention provides a pack for supplying carbon dioxide to a skin, capable of storing carbonate and acid in an unreacted mixed state without being degenerated according to a change with the passage of long time and easily usable. The pack is formed by successively applying and drying an acid-coated layer and a carbonate-coated layer on one side surface of a non-woven fabric and by laminating a waterproof film on the other side surface thereof. Otherwise, the pack is formed by including a first non-woven fabric configured to have one side surface on which a carbonate-coated layer is formed; a second non-woven fabric configured to have one side surface on which an acid-coated layer is formed; and a waterproof film, wherein the first non-woven fabric and the second non-woven fabric are laminated such that the carbonate-coated layer and the acid-coated layer face each other, and the waterproof film is attached on one outer surface of the lamination.
