Adhesives are widely used in industrial world. However, it is difficult to characterize their mechanical properties because those strongly depend on enviromental conditions such as temperature, humidity and strain rate. In this paper, we focus on the inter facial strength of adhesives and investigate the rate dependence of the interfacial strength by peel tests. The results show that, in low rate case (under 10^<-2>mm/s), the interfacial strength was constant and, in middle rate case (10^<-2> to 10^3mm/s), the interfacial strength increased with the peel rate. Over 10^3mm/s case, the interfacial strength became lower than those in middle rate cases. From the observation of peeling front by high speed video camera, the deformation behavior of adhesives changed with the peel rate.
