Disclosed is a drip irrigation emitter attached to a water supply tube for watering a plant little by little. The drip irrigation emitter comprises an outer member and a slow flow member. The outer member 10 includes a guide hole 16, an inlet and an outlet 18. The slow flow member 20 is removably attached to the guide hole 16 of the outer member 10. The slow flow member 20 includes a main body 21, a passage 23, a piercing portion 25, and a plurality of notches 24. The passage 23 is helically formed around the body 21 and has a certain cross-sectional area. The piercing part 25 is attached to the main body 21 and protrudes from the entrance. The notch 24 is formed around the main body 21 between the first end face of the main body 21 and the piercing portion 25 and communicates with the passage 23. Each notch 24 has a smaller cross-sectional area than the passage 23 and prevents the passage 23 from being blocked by impurities. The piercing part 25 can pierce the water supply tube 30 directly for accurate alignment with the plant. [Selection] Figure 4【課題】植物に少しずつ水やりするための給水チューブに取付けられる点滴灌漑エミッタを提供する。【解決手段】点滴灌漑エミッタは外側部材１０及び緩流部材２０を具える。外側部材１０は導孔１６、入口及び出口１８を具える。緩流部材２０は外側部材１０の導孔１６に取外し可能に取付けられる。緩流部材２０は本体２１、通路２３、突き刺し部２５、及び複数の切欠き２４を具える。通路２３は本体２１の周りにらせん状に形成され或る断面積を有する。突き刺し部２５は本体２１に取付けられ、入口から突出している。切欠き２４は、本体２１の第１端面と突き刺し部２５の間で、本体２１の周りに形成され、通路２３と連通する。切欠き２４の１つ１つは通路２３よりも小さな断面積を有し、通路２３が不純物によって塞がれることを防ぐ。突き刺し部２５は植物との正確な位置合わせのために給水チューブ３０に直接突き刺すことができる。【選択図】図４
