Abstract
The present invention relates to an emitter that can properly exhibit a flow rate adjustment function even when produced by molding a resin material having low hardness. The emitter has an emitter body and a base part stored in the emitter body. The emitter body comprises a water intake part, a reduced-pressure flow path groove, a storage part, and a diaphragm part. The base part has a base, a communication hole, and a deformation prevention part that is disposed protruding from the reverse surface to the surface of the base which the diaphragm part deformed by the pressure of a drip irrigation liquid contacts, and when the diaphragm part contacts the base by the pressure of the drip irrigation liquid, contacts the tube to prevent the base from being deformed by the pressure of the drip irrigation liquid.
