PROBLEM TO BE SOLVED: To provide a nebulizer which supplies high oxygen concentration gas by increasing flow volume of oxygen gas and also generates fine aerosol irrespective of changes in flow volume of oxygen gas. SOLUTION: The nebulizer A comprises a nozzle member 11 for ejecting oxygen gas from an orifice 11b, an aerosol generating member 12 which is arranged on a position corresponding to the orifice, sucks water by means of flow of the oxygen gas ejected from the orifice and changes the sucked water into fine aerosol, and a window 9 and a slit 10 for sucking air when oxygen gas is ejected from the orifice of the nozzle member. In addition to the orifice 11b, the nozzle member 11 has an oxygen gas discharge section which is formed in a direction different from the orifice and discharges oxygen gas in response to the pressure of the supplied oxygen gas.
