PROBLEM TO BE SOLVED: To provide a method for processing an adherend using a thermopeelable double-sided adhesive sheet provided on one side with a thermoexpansible adhesive layer containing thermoexpansible microspheres, enabling the surface smoothness of the adherend to be kept in processing it. SOLUTION: The method involves using the thermopeelable double-sided adhesive sheet with one side of a base sheet bearing the thermoexpansible microsphere-containing thermoexpansible adhesive layer and the other side an adhesive layer, and comprises the steps of (A) laminating a substrate on the thermoexpansible adhesive layer surface of said adhesive sheet and laminating the adherend on the adhesive layer surface, (B) processing the adherend, (C) peeling said adhesive sheet off the substrate by heat treatment, and (D) peeling said adhesive sheet off the adherend after processed.
