Beschreibung
Zusammenfassung:	In an aeration apparatus according to the present invention, water-repellent treatment is applied at least to one of an opening and vicinity thereof of a slit (12) formed in a diffuser membrane of an aeration nozzle, thereby providing a water-repellent layer (150), so that the inflow of seawater into the slit (12) is prevented and precipitation of calcium sulfate or the like in the slit is suppressed and avoided. As a material for forming the water-repellent layer (150), for example, a talc coating layer using talc, a fluorine coating layer coated with a fluorine resin, silicone coating layer coated with a silicone resin, and a wax coating layer coated with wax can be mentioned.
