Zusammenfassung:	To provide an adhesive tape that has excellent heat resistance even when using a base material containing polyolefin resin such as polyethylene resin.SOLUTION: An adhesive tape contains a base material containing polyolefin resin, and a radiation-curable adhesive layer provided on at least one side of the base material. The adhesive layer has a gel fraction X2 of 10% or more and the base material has a gel fraction Y of 2% or more. The adhesive layer has a thickness of 10-50 μm and is formed from an adhesive composition containing an acrylic polymer, a crosslinker and a tackifier.SELECTED DRAWING: None 【課題】ポリエチレン樹脂などのポリオレフィン系樹脂を含有する基材を使用した場合であっても耐熱性に優れる粘着テープを提供する。【解決手段】ポリオレフィン系樹脂を含有する基材と、該基材の少なくとも一方の面に設けられた放射線硬化型粘着剤層とを備えた粘着テープであって、前記粘着剤層のゲル分率Ｘ２が１０％以上、前記基材のゲル分率Ｙが２％以上である、粘着テープ。前記粘着剤層の厚みが１０〜５０μｍであり、アクリル系重合体、架橋剤及び粘着付与剤を含有する粘着剤組成物により形成される、前記粘着テープ。【選択図】なし
