A gas mist inhaler, 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 inhaler is provided with a gas supply means (10), a gas mist generating means (30), and an inhalation 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 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.Cette invention concerne un inhalateur de brume gazeuse comportant une section dintroduction de gaz qui augmente la pression dapprovisionnement dune brume gazeuse avec un générateur de brume gazeuse, et qui permet de simplifier la structure et de réduire les coûts. Linhalateur de brume gazeuse est équipé dun système dapprovisionnement en gaz (10), dun système générant la brume gazeuse (30), et dun élément dinhalation (50). Le système générant la brume gazeuse (30) comprend les éléments suivants, formés dun seul tenant : une partie de connexion reliée au système dapprovisionnement en gaz (10) une partie ramifiée qui oblige le flux du gaz provenant de la partie de connexion à bifurquer une partie de stockage de liquide une buse qui évacue lun des flux de gaz ayant bifurqué au niveau de la partie ramifiée un tube da
