A jet regulator (100) including a jet regulator housing (2) is disclosed, in the housing interior of which a perforated plate (5) is provided with a plurality of flow-through holes (6) for dividing the through-flowing water. The jet regulator described is characterized in that at least one flow-through hole (6) extends conically towards its outflow side in at least one outflow-side hole section. It is also possible for flow obstacles to be provided on the outflow side of the perforated plate (5) in the jet regulator housing (2) and/or on the outflow front face of the jet regulator housing, which are arranged or concentrated there in a central or middle region and which deflect the through-flowing water into an outer annular zone. This jet regulator (100) enables an aerated and thereby sparkling-soft water jet to be generated even with low flow-through performance and low water pressure.
