Abstract
Provided are a UV curable composition which can be cured without undergoing a high-temperature heating step and has excellent adhesiveness and mechanical strength; and a sheet using the same. This UV curable composition includes a rubber component having a diene skeleton, a photopolymerization initiator, and a cross-linking agent, wherein the rubber component having a diene skeleton contains a solid rubber component and a liquid rubber component at 25° C. The UV curable composition can be cured by UV irradiation in a short time, and can thus be applied to not only an adherend having high heat resistance but also a wide range of members.
