Abstract
An emitter forms a flow path that runs to a discharge part from a water collecting part for receiving an irrigation liquid in a tube. The flow path includes a flow rate control part which includes: an end surface including a concave inclined surface that faces a film for receiving the pressure of the liquid inside the tube; a hole that opens at the center of the flow volume control part and connects to the discharge part; and a groove crossing the inclined surface and running to the hole. When the film adheres to the inclined surface as a result of the pressure of the irrigation liquid inside the tube, the flow volume of the irrigation liquid inside the emitter is controlled so as to be a volume that can pass through the groove.
