To provide a technique of efficiently catching insects while reducing time and effort of maintenance.SOLUTION: The insect trap 1 includes: a light source 12 for emitting light to one side in the axial direction； a fan 15 which, on one side in the axial direction of the light source 12, discharges to one side in the axial direction the gas of the other side in the axial direction； a reflection member 14, on one side in the axial direction of the light source 12 and on the other side in the axial direction of the fan 15, reflects light from the light source 12 to the outer side in the radial direction； a cylindrical part 241 for covering the outer side in the peripheral direction of the fan 15； and an insect trap member installation part 245 which installs an air-permeable insect trap member 16 in a position covering an opening on one side in the axial direction of the cylindrical part 241. By reflecting light from the light source to the outer side in the radial direction, the light reaches a wide range in the horizontal direction. In addition, as attracting insects by the light and taking in air by the fan, the insect trap can catch insects in places away from the insect trap. Furthermore, since an attractant or an adhesive sheet that requires replacement is unused as an indispensable component, the insect trap can efficiently catch insects while reducing time and effort of maintenance.SELECTED DRAWING: Figure 4【課題】メンテナンスの手間を軽減しつつ、効率的に捕虫できる技術を提供する。【解決手段】この捕虫器１は、軸方向一方側へ光を出射する光源１２と、光源１２の軸方向一方側において軸方向他方側の気体を軸方向一方側へと排出するファン１５と、光源１２の軸方向一方側かつファン１５の軸方向他方側において光源１２からの光を径方向外側へと反射させる反射部材１４と、ファン１５の周方向外側を覆う筒状部２４１と、通気性を有する捕虫部材１６を筒状部２４１の軸方向一方側の開口を覆う位置に取り付ける捕虫部材取付部２４５とを有する。光源からの光を径方向外側に反射することにより、水平方向の広い範囲に光が届く。また、光により昆虫を誘引し、ファンを用いて吸気するため、捕虫器から離れた場所にいる昆虫も捕らえられる。また、交換が必要な誘引剤や粘着シートを必須の構成としていないため、メンテナンスの手間を軽減しつつ、効率的に補虫できる。【選択図】図４
