PROBLEM TO BE SOLVED: To increase a bactericidal effect of a fluid discharged from a discharge part.SOLUTION: The sterilizer includes: a discharge part for discharging a fluid an ultraviolet-permeable flow channel member in which the fluid discharged from the discharge part flows and a light source part which includes a light-emitting element for irradiating ultraviolet light to the fluid flowing in the flow channel member. The light-emitting element is disposed along a circumferential direction of an outer peripheral surface of the flow channel member in such a manner that a light-emitting surface of the light-emitting element faces the fluid flowing in the flow channel member.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】吐出部から吐出される流体の殺菌効果を高める。【解決手段】実施形態の殺菌装置は、流体を吐出するための吐出部と、紫外線透過性を有して吐出部から吐出される流体が流れる流路部材と、流路部材を流れる流体に紫外線を照射するための発光素子を有する光源部と、を備える。発光素子は、流路部材の外周面の周方向に沿って配置され、発光素子の発光面が、流路部材を流れる流体に対向して配置されている。【選択図】図3
