Abstract
[Problem] This is to provide an adhesive sheet having curved surface followability and chemical resistance. [Means for solving] The adhesive sheet is an adhesive sheet having at least a substrate and an adhesive layer, a load at the time of 5% elongation of the substrate is 15 N/cm or less, a stress relaxation rate of the substrate by elongating to 10%, stopping the elongation at that state and after lapsing 600 seconds is 40% or more and 100% or less, and a chemical weight increased ratio of the substrate is 60% or less.
