Abstract: The present invention addresses the problem of providing: an emitter that can be placed within a tube without aligning discharge parts of the emitter, is reduced in thickness while having a function for adjusting the flow rate, and is less likely to inhibit irrigation fluid flow. An emitter for solving the above problem is joined to the inner wall surface of a tube through which an irrigation fluid flows, and is used to discharge the irrigation fluid within the tube from a discharge port to the outside of the tube. The emitter has: at least one intake part; one discharge amount adjustment part; one discharge groove; and a plurality of discharge parts. The plurality of discharge parts are disposed symmetrically on both sides of the center of the emitter in a plan view.
