An apparatus constructed in a simple structure and capable of generating fine air bubbles and includes an apparatus body having a circular column-like internal space defined by a cylindrical inner surface and circular inner surfaces. At least one internal cylindrical member can be disposed within the internal space away from the cylindrical inner surface. A first fluid introduction section can inject a first fluid into a tubular space between the cylindrical inner surface and the internal cylindrical member toward a circumferential direction. A second fluid introduction section and a gas and liquid mixture discharge port can be disposed in the circular inner surfaces, respectively.
