Provided are: a nebulizer system in which a bottle, heater device, and nebulizer adapter are easy to connect and there is no drain tube exposed to the outside and getting in the way； and a heater device suitable for use in said nebulizer system. Said nebulizer system (1) is provided with: a bottle (2), with a mouth (25) at the top thereof, in which a liquid is stored； a heater device (3) that can be connected to the mouth (25) of the bottle； and a nebulizer adapter (4) that can be connected to the heater device (3). The bottle (2) is provided with a dip tube (22) immersed in the liquid stored inside. With a space (226) provided at the top end of the dip tube (22), said space connecting the inside and outside of the bottle (2) through the mouth (25) thereof, the top end of the dip tube (22) is disposed inside the walls of the mouth (25) of the bottle. The nebulizer adapter (4) is provided with: a nozzle member (42) that has a nozzle (421) through which a gas is injected； and an aerosol-forming member (43) that is disposed at a location corresponding to the aforementioned nozzle (421) and that, by means of the stream of gas injected via the nozzle (421), suctions up the liquid in the bottle (2) via the dip tube (22) and the heater device (3) and turns said liquid into a fine aerosol. The following are provided inside the heater device (3): a channel (32), one end of which is connected to the top end of the dip tube (22) and the other end of which is connected to the aerosol-forming member (43)； a heating unit (33) that heats said channel (32)； and a drain tube (35), one end of which is disposed opposite the abovementioned space (226) and the other end of which returns liquid that was not aerosolized in the nebulizer adapter (4) back to the bottle (2).La présente invention concerne un système de nébuliseur dans lequel une bouteille, un dispositif de chauffage, et un adaptateur pour nébuliseur sont faciles à connecter, et il n'y a pas de tube de drainage exposé sur l'ex
