Abstract: An adhesive sheet includes an adhesive layer provided on at least a part of one side or both sides of a base, wherein the adhesive layer is a foamable epoxy adhesive layer containing a polyfunctional epoxy resin and an epoxy resin other than the polyfunctional epoxy resin, and a hot-melt protective layer is provided on at least a part of a surface of the adhesive layer away from the base, and the protective layer contains at least one additive selected from the group consisting of an antistatic agent, a lubricant, and a metal deactivator.

Abstract: Disclosed is an adhesive sheet having an adhesive layer 2 on at least a part of one side or both sides of a base 1, characterized in that a protective layer 3 is provided on at least a part of the surface of the adhesive layer 2. The adhesive layer 2 is preferably an expandable adhesive layer, and the protective layer 3 is preferably a hot-melt protective layer. The protective layer 3 may contain a functional component such as an antistatic agent, a coloring agent, a hard coating agent, a lubricant, a heat dissipating material, a metal deactivator and an antioxidant. This adhesive sheet can protect an adhesion surface and does not cause blocking and skin disorders even if a release liner is not used, and is also excellent in various functions.
