Problem to be solved: to obtain an insect repellent sheet which is excellent in the suppression of ultraviolet light deterioration and is difficult to recognize.The caterpillar sheet is provided on the substrate and at least one of the surfaces of the substrate, and includes a reflective layer including metallic material and an adhesive layer provided on the surface opposite to the base of the reflective layer.The reflection layer preferably has an average reflectivity of 45% or more to the ultraviolet light in the range of 330 nm to 370 nm or less, and the average transmittance to ultraviolet light in the range of 290 nm or 330 nm or less is preferably 0.7% or less.Diagram【課題】紫外光劣化抑制性に優れ、捕捉された虫が視認しにくい捕虫シートを得る。【解決手段】捕虫シートは、基材と、基材の少なくとも一方の面に設けられ、金属材料を含む反射層と、反射層の基材と反対側の面に設けられた粘着層と、を備える。反射層は、波長が３３０ｎｍ以上３７０ｎｍ以下の範囲の紫外光に対する平均反射率が４５％以上であり、波長が２９０ｎｍ以上３３０ｎｍ以下の範囲の紫外光に対する平均透過率が０．７％以下であることが好ましい。【選択図】図１
