PROBLEM TO BE SOLVED: To provide an insect-catching device for ejecting an ultraviolet light of a high attraction of a noxious insect efficiently.SOLUTION: An insect-catching device comprises: a housing having an opening and a collection part 20 for collecting a noxious insect having invaded from an opening a lamp 16 arranged in the housing for ejecting an ultraviolet light and a reflection board 13 for reflecting an ultraviolet light ejected from the lamp toward the opening. The reflection board has a multilayer film for reflecting the light of a wavelength of a region, to which an ultraviolet light belongs, and for transmitting a light of another wavelength.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】害虫の誘引性の高い紫外光を効率的に出射する捕虫装置を提供する。【解決手段】開口と、開口から侵入した害虫を捕集する捕集部20とを有する筐体と、筐体内部に配置され、紫外光を出射するランプ16と、ランプから出射した紫外光を、開口に向けて反射させる反射板13とを備え、反射板は、紫外光の属する領域の波長の光を反射し、その他の波長の光を透過する多層膜を有することを特徴とする捕虫装置。【選択図】図3
