The invention is to provide a gas mist pressure bath system, which is possible to control the amount of gas and liquid, pressure and others, and cause a gas mist to be absorbed through a skin and mucous membrane of a human living body under an optimum condition. The present system comprises a gas supply means 11, a gas mist supply means 31 for generating and supplying the gas mist by pulverizing and dissolving the gas and the liquid supplied from the gas supply means 11, and a living-body cover member 41 for covering the skin and mucous membrane of the living body and forming a space of sealing inside the gas mist supplied from the gas mist supply means 31, wherein the gas mist supply means 31 comprises a liquid storing part 32B, a gas mist storing part 32A, a nozzle part 33 of jetting gas from its front end, a suction pipe 36A of sucking up the liquid until the nozzle front end, and a baffle member 35 provided opposite the nozzle front end, and that the gas jetted from the nozzle part 33 causes the liquid sucked up by the suction pipe 36A until the nozzle front end to collide with the baffle member 35 and turn out the gas mist by pulverizing and dissolving.
