UV-curable resin composition and UV-curable sheet

Provided are: a UV-curable resin composition which can be cured without a high-temperature heating step and which has excellent adhesiveness (adhesive force); and a sheet which uses the UV-curable resin composition. A UV-curable resin composition containing a rubber component having a diene skeleton, a photopolymerization initiator, a cross-linking agent, and a tackifier, the UV-curable resin composition containing a rubber component that is solid at 25 DEG C and a rubber component that is liquid as the rubber component having a diene skeleton. Since the UV-curable resin composition can be cured by UV irradiation for a short time, the UV-curable resin composition can be applied not only to an adherend having high heat resistance but also to a variety of components. 本发明提供一种能不经过高温的加热步骤而固化、且具有优异的黏接性(黏着力)的UV固化型树脂组合物及使用了其的片材。在含有具有二烯骨架的橡胶成分、光聚合引发剂、交联剂与增黏剂的UV固化型树脂组合物中，含有在25℃为固体状的橡胶成分及液状的橡胶成分作为具有二烯骨架的橡胶成分。由于可通过短时间的UV照射使上述UV固化型树脂组合物固化，因此不仅能应用于耐热性高的被黏接体而且能应用于多种部材。
