摘要:
An emitter (120) includes a flow path from a water intake path (221), which is for taking in irrigation liquid within a tube, to a recessed part (251). This flow path includes a recessed surface part (242) closed, without contact, by a film (300). A channel (243) that forms a reduced pressure flow path included in the above flow path is formed on the surface of the recessed surface part (242). If the film (300) is pressed by the pressure of the irrigation liquid in the tube (110) and adheres to the recessed surface part (242), the flow rate of the irrigation liquid inside the emitter (120) is controlled to an amount that can pass through the channel (243).
