摘要：Provided is a heat-expandable removable acrylic pressure-sensitive adhesive tape that has high normal-state adhesive power when bonded independently of whether the adherend has or does not have irregular surface and permits easy separation when the bonded region is separated and disassembled by lowering the adhesive power by heating, that permits easily separation-decomposition, even after long-term storage at high temperature. The heat-expandable removable acrylic pressure-sensitive adhesive tape or sheet according to the present invention is a heat-expandable removable acrylic pressure-sensitive adhesive tape or sheet having a heat expanding agent-containing pressure-sensitive adhesive layer on or above at least one face of a bubble-bearing microparticle-containing viscoelastic material, characterized in that the heat expanding agent contains a heat-expandable microsphere having a shell-substance glass transition temperature of 92° C. or higher.
