摘要:
A cross-linked silicone adhesive sheet has stability of peeling surfaces during peeling protective films away from both sides of the sheet. An adhesive sheet of a cross-linked silicone has protective films on both sides of the sheet. The protective films each have a thickness of 100 μm or less. A force of peeling of the protective films from the sheet is equal to or below 5.0 N/m. The difference between peeling forces of the films is equal to or exceeds 0.2 N/m. A method of manufacturing the adhesive sheet of a cross-linked silicone includes the steps of forming a film-like body by placing a cross-linkable silicone composition in a layer having a thickness of 100 μm or less between two protective films of different materials and then cross-linking the composition.
