A gas mist pressure bathing system, which integrates a gas introduction part for increasing the supply pressure of a gas mist with a gas mist generator and enables the structure to be simplified and costs to be reduced, is provided. The gas mist pressure bathing system is provided with a gas supply means (10), a gas mist generating means (30), and a living body cover member (50). The gas mist generating means (30) is provided with, in an integrally formed manner: a connection part that connects to the gas supply means (10) a branched part that forces the gas flow from the connection part to branch off a liquid storage part a nozzle that discharges one of the gas flows that branched off at the branched part a liquid-suctioning tube that transfers the liquid to the nozzle tip a collision member that generates a gas mist by causing the liquid blown upwards by the gas flow discharged by the nozzle to collide a merging part that merges the gas from above with the gas mist that was generated a gas introduction part that guides the other gas flow that branched off at the branched part to the merging part and a gas mist discharge part that collects and discharges the gas mist and gas that were generated.La présente invention concerne un système de bain sous pression de brume gazeuse, qui comprend une partie dintroduction de gaz destinée à accroître la pression dalimentation dune brume gazeuse avec un générateur de brume gazeuse, et qui permet de simplifier la structure et de réduire les coûts. Ledit système de bain sous pression de brume gazeuse est pourvu dun moyen dalimentation en gaz (10), dun moyen de production de brume gazeuse (30), et dun élément de couverture dorganisme vivant (50). Le moyen de production de brume gazeuse (30) est pourvu des éléments suivants, formés dun seul tenant : une partie de raccordement reliée au moyen dalimentation en gaz (10) une partie ramifiée qui pousse le flux de gaz provenant de la partie de raccordement à bifurquer une partie de st
