Abstract
This emitter () includes a channel which spans to a recessed section (), from an intake path () for receiving an irrigation liquid inside a tube. The channel includes an aperture () which is closed by a lid () disposed so as to not be in contact with a film (). A groove is formed at the periphery of the aperture (). When the film () is pressed as a result of the pressure of the irrigation liquid inside the tube, and the lid () closes the aperture (), the flow rate of the irrigation liquid inside the emitter () is controlled so as to be the amount capable of passing through the groove. This flow-rate control continues until the pressure difference in the channel between a side upstream with respect to the lid () and a side downstream with respect to the lid () has been sufficiently reduced.
