Abstract: The adhesive sheet includes an adhesive layer (A1L) in solid form at 18° C., wherein the adhesive layer (A1L) contains an epoxy resin, at least one surface of the adhesive layer (A1L) has a tackiness agent region (A2R) formed by partially providing a tackiness agent (A2), and a region where the tackiness agent region (A2R) is not formed on the surface is an adhesive-layer-exposed region (A1LR) where a surface of the adhesive layer (A1L) is exposed. This adhesive sheet has excellent temporary fixability at the time of sticking (a characteristic that exhibits the tackiness force necessary for temporary fixation) and adhesive force after heat curing.

Abstract: Disclosed are an adhesive sheet production method of having a step of applying an adhesive composition in a stripe shape on one or both sides of a base to form an adhesive layer, wherein the adhesive composition having viscosity regulated is used for the applying so that the ratio (Te/T) of the thickness (Te) at the edge portion of the stripe-shaped adhesive layer to the thickness (T) of the portion other than the edge portion is 1.8 or less after applying the adhesive composition and drying; and an adhesive sheet in which the ratio (Te/T) of the thickness (Te) at the edge portion of the stripe-shaped adhesive layer obtained as described above to the thickness (T) of the portion other than the edge portion is 1.8 or less.

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.
