Disclosed is a gas mist mask device which is compact and inexpensive, and in which the mist bath of a face and eyes can be performed using the physiological action of oxygen and carbon dioxide. Specifically disclosed is a gas mist mask device which is provided with: a gas supply means (110) for supplying oxygen, carbon dioxide, or the mixed gas (hereinafter, referred to as "gas") of oxygen and carbon dioxide a gas mist generating means (120) that is connected to the gas supply means (110), stores a liquid in the inside thereof, and generates mist (hereinafter, referred to as "gas mist") in which the stored liquid and the gas are crushed and dissolved and a mask member (130) that has a mask body (131) provided with a first sheet that allows the passage of the gas mist therethrough and a second sheet that does not allow the passage of the gas mist therethrough, and a fixing unit (138) for fixing the mask body (131) so that the first sheet extends toward the eye section or the face section of a human body, wherein the gas mist generating means (120) brings the gas mist into contact with the eye section or the face section of the human body by supplying the gas mist between the first sheet and second sheet of the mask member (130).Linvention concerne un dispositif de masque de brume gazeuse de petite taille et dun coût modéré permettant de réaliser un bain de brume du visage et des yeux en utilisant laction physiologique de loxygène et du dioxyde de carbone gazeux. Le dispositif de linvention est équipé: dun moyen (110) dapprovisionnement en gaz qui assure lapprovisionnement en oxygène, dioxyde de carbone gazeux, ou gaz mélangé doxygène et dioxyde de carbone gazeux (appelé ci-après "gaz") dun moyen (120) de production de brume gazeuse qui tout en étant relié au moyen (110) dapprovisionnement en gaz recueille un liquide dans une partie interne et produit une brume (appelée ci-après "brume gazeuse") dans laquelle le liquide recueilli et ledit gaz sont pulvérisés et dissou
