PROBLEM TO BE SOLVED: To provide an ultraviolet sterilization device using a DUV-LED as an ultraviolet light source which can be used as a portable device and can improve operability of sterilization of an object.SOLUTION: An ultraviolet sterilization device comprises an ultraviolet sterilization unit which includes: a housing having an opening an ultraviolet transmitting window which transmits ultraviolet light, has an inner surface and an outer surface on the opposite side of the inner surface, and arranges the inner surface to face the inside of the housing to close the opening of the housing a light source which has at least one ultraviolet light emitting diode to emit ultraviolet rays as a band-shaped light flux and scanning means which, by irradiating the ultraviolet rays emitted from the light source while shifting a position, from which the ultraviolet rays emitted from the light source is incident to the ultraviolet transmitting window, in a direction intersecting the width direction of the band-shaped light flux, can irradiate the ultraviolet rays emitted from the light source onto the whole surface of the inner surface of the ultraviolet transmitting window from the inside of the housing. The ultraviolet sterilization device performs sterilization by irradiating the ultraviolet rays onto an object to be disinfected placed opposite the outer surface of the ultraviolet transmitting window.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 紫外線光源としてDUV-LEDを用いた紫外線殺菌装置であって、携帯用としても使用可能であり、更に物の殺菌の操作性を向上させることが可能な、紫外線殺菌装置を提供する。【解決手段】 開口部を有する筐体と、内側面および該内側面と反対側の外側面を有し、筐体の開口部を塞ぐように内側面を筐体の内部に向けて配置された、紫外線を透過する紫外線透過窓と、一つ以上の紫外発光ダイオードを有し紫外線を帯状の光束として出射する光源と、光源からの紫外線が紫外線透過窓に入射する位置を帯状の光束の幅方向に交差する方向にずらしながら光源からの紫外線を照射することによって筐体の内部から紫外線透過窓の内側面の全面にわたって光源からの紫外線を照射することができる走査手段とを有する紫外線殺菌ユニットを含み、紫外線透過窓の外側面に対向して配置された被殺菌体に紫外線を照射して殺菌を行う、紫外線殺菌装置。【選択図】図1
