The emitter 120 has: a screen part for capturing suspended matters in water in the tube; a water intake amount adjusting part for preventing inflow of low-pressure liquid; a decompression part which decompresses the pressure of the taken water; a discharge amount adjusting part which adjusts a decompressed flow rate of water corresponding to water pressure in the tube; and a discharge part through which water is supplied at adjusted flow rate, in a water intake part thereof. The screen part is constituted of slits 301 and a recess which crosses the slits 301 in a plan view. the discharge part includes an entry prevention part for preventing entry of foreign matters from the discharge port of the tube.SELECTED DRAWING: Figure 5 |
