A heat-peelable adhesive sheet which comprises ansubstrate and, formed on at least one side thereof, a heat-expandablenlayer containing heat-expandable microspheres andnan adhesive layer comprising an adhesive substance and in whichnthe substrate has heat resistance and stretchability can be usednto cut an adherend so as to form and secure a sufficient spacenbetween the resultant cut pieces and can withstand a heatntreatment for expanding the heat-expandable layer.nConsequently, the adhesive sheet can heighten the operatingnefficiency and working efficiency in the step of separating andnrecovering the cut pieces. |
