This emitter has an emitter body and a pedestal. The emitter body includes: a water intake part for introducing irrigation liquid; a pressure reducing flow passage groove which is for forming a pressure reducing flow passage which communicates with the water intake part and allows the irrigation liquid to flow out while reducing the pressure of the irrigation liquid; an accommodation part which communicates with the pressure reducing flow passage groove and into which the irrigation liquid flows while the pedestal is accommodated therein; and a flexible diaphragm part which approaches the pedestal upon receiving the pressure of the irrigation liquid inside a tube while the pedestal is accommodated in the accommodation part. The pedestal has through-holes for discharging the irrigation liquid that flowed into the accommodation part. The emitter body and the pedestal are connected through a hinge part.
