Zusammenfassung:	To provide a fluid sterilization device which can be reduced in its size and can cope with ultraviolet ray deterioration of a housing.SOLUTION: A housing main body 12 and an outer cover 14 form a housing. A straight pipe 18 and a light source unit 19 are inserted into the housing in an axial direction. A derivation channel 35 is formed in the housing, and is communicated with a notch 181 which is formed on the light source unit 19 side of the straight pipe 18. A shield ring 20 has ultraviolet ray resistance greater than that of the housing. A taper part 201 of the shield ring 20 defines the derivation channel 35 and protects the housing from ultraviolet ray which leaks from the notch 181 to an external part of the straight pipe 18.SELECTED DRAWING: Figure 5B 【課題】小型化を図りつつ、筐体の紫外線劣化に対処する流体殺菌装置を提供する。【解決手段】筐体本体１２及びアウタカバー１４は筐体を構成している。直管１８及び光源装置１９は、筐体内に軸方向に内挿されている。導出流路３５は、筐体内に形成され、直管１８の光源装置１９側に形成されている切欠き１８１に連通している。遮蔽リング２０は、筐体より高い紫外線耐性を有する。遮蔽リング２０のテーパ部２０１は、導出流路３５を画成しているとともに、切欠き１８１から直管１８の外に漏れてくる紫外線に対して筐体を保護する。【選択図】図５Ｂ
