Abstract
An emitter () forms a flow path that runs to a discharge part () from an intake part () for receiving an irrigation liquid in a tube. The flow path includes a flow volume 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 ().
