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 must 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.
