Provided is a heat-resistant adhesive sheet in which deformation of the adhesive sheet as a result of heating does not readily occur. The adhesive sheet, which is formed by laminating an adhesive agent layer on a substrate, is characterised in that: the substrate exhibits a heat shrinkage property; the adhesive agent layer includes a (meth)acrylic acid ester copolymer, a photopolymerisable compound, a polyfunctional isocyanate curing agent, and a photopolymerisation initiator; and a tackifying resin is not substantially included. Even if heated, deformation does not occur in this adhesive sheet. Furthermore, a tackifying resin is not substantially included in the adhesive agent, and softening therefore does not occur in the adhesive agent layer, even if heated. |
