The present invention provides a foamed-water generating aerator which is capable of generating good-quality foamed water containing fine, homogeneously distributed air bubbles. The foamed-water generating aerator (100) is fitted to a water discharge pipe to turn water being discharged into foamed water. A circumferential water flow curtain forming portion (110) includes a gap (111), through which water flows, and forms a three-dimensional circulating water flow curtain (112) in which an accelerated water-flow issuing downstream from the gap (111) is continuous in the circumferential direction. An air cavity (120) is provided at some intermediate point in a water-flow path as a place for forming the circulating water flow curtain (112) and sustains an air-filled condition even when a water-flow of the circulating water flow curtain enters therein. Air is drawn through an air ventilation hole (140) into an enclosed space, the enclosed space being defined by the circulating water flow curtain (112) formed in the air cavity (120) and a surrounding wall surface, is mixed with the circulating water flow curtain (112) to thereby form the foamed water.
