Abstract
This emitter () comprises: a first flow rate adjustment unit which adjusts the flow rate of an irrigation liquid according to the deformation of a first diaphragm (); and a second flow rate adjustment unit which adjusts the amount of irrigation liquid ejected (discharged) from the emitter () according to the deformation of a second diaphragm (). The first diaphragm () has a projection spaced apart by a space from a hole which is a flow path for the irrigation liquid. The projection has an inverted truncated cone shape and is formed so that the space widens as the projection goes into the hole.
