[Problem] The present invention provides a pressure-sensitive adhesive sheet having curved surface followability and chemical resistance. [Solution] A pressure-sensitive adhesive sheet comprising at least a base material and an pressure-sensitive adhesive layer, a load at 5% elongation of the base material is 15 N/cm or less, and the base material is stretched to 10 N/cm %, the stress relaxation rate after 600 seconds from the elongation stop in this state is 40% or more and 100% or less, and the chemical weight increase rate of the base material is 60% or less. |
