PROBLEM TO BE SOLVED: To provide a sterilization device of flowing water having an enhanced sterilization efficiency of UV light.SOLUTION: A sterilization device of flowing water includes a straight pipe 20 to partition a processing passage 16, a light source (first light source 41 or second light source 42) that is installed on at least one end of both ends (upstream side end 21, downstream side end 22) of the straight pipe 20 and emits UV light toward the processing passage 16 in the axial direction of the straight pipe 20, and a bubble generator 50 that is installed upstream of the processing passage 16 and mixes bubbles 70 with water flowing into the processing passage 16. The device may further include a window member (first window member 25 or second window member 26) to separate the light source from the processing passage.SELECTED DRAWING: Figure 1 【課題】紫外光による殺菌効率を高めた流水殺菌装置を提供する。【解決手段】処理流路１６を区画する直管２０と、直管２０の両端部（上流側端部２１、下流側端部２２）の少なくとも一方に設けられ、処理流路１６に向けて直管２０の軸方向に紫外光を照射する光源（第１光源４１または第２光源４２）と、処理流路１６より上流に設けられ、処理流路１６に流入する水に気泡７０を混合させるバブル発生装置５０と、を備える。光源と処理流路の間を区画する窓部材（第１窓部材２５または第２窓部材２６）をさらに備えてもよい。【選択図】図１
