PROBLEM TO BE SOLVED: To provide a self-adhesive sheet for trapping insects, having a self-adhesive layer for trapping insects on one surface of a base material sheet, capable of efficiently trapping and killing flying insect pests, and having proper processability and preservability, in particular, the self-adhesive sheet that can be suitably used for an ultraviolet-attracting type insect trap, and having superior ultraviolet transparency and ultraviolet deterioration resistance.SOLUTION: The self-adhesive sheet is such that one side of a base material sheet is provided with a self-adhesive layer, including (A) a polyolefin-based polymeric elastomer 5,000-50,000 for the number-average molecular weight and (B) 20 pts, mass or higher but lower than 200 pts.mass, with respect to 100 pts.mass of the component A, of a polymerized softening agent 300-4,000 in number-average molecular weight. This self-adhesive sheet has a shearing force of 5-70 N/35 mm×35 mm, when the self-adhesive layer surfaces are superposed on each other.COPYRIGHT: (C)2009,JPO&INPIT【課題】基材シートの一方の面に捕虫用の粘着剤層を有し、飛翔性害虫を効率よく捕殺することができると共に、加工性や保存性が良好な捕虫用粘着シート、特に紫外線誘引型の捕虫器に好適に使用し得る紫外線透過性及び耐紫外線劣化性に優れる捕虫用粘着シートを提供する。【解決手段】基材シートの一方の面に、(A)数平均分子量が5,000~50,000であるポリオレフィン系高分子エラストマーと、その100質量部に対し、(B)数平均分子量が300~4,000である重合型軟化剤20質量部以上200質量部未満を含む粘着剤層を有する粘着シートであって、当該粘着シートの粘着剤層面同士を重ね合わせた場合のせん断力が、5~70N/35mm×35mmであることを特徴とする捕虫用粘着シートである。【選択図】なし
