Zusammenfassung:This method for producing a cured sealant by using an adhesive sheet having: a base material (Y) equipped with a non-expandable base material layer (Y2) and an expandable base material layer (Y1) that contains expandable particles; and a first adhesive layer (X1) and a second adhesive layer (X2). The method comprises steps (1)-(3). Step (1): A step for attaching the adhesive surface of the first adhesive layer (X1) to a hard support body, and placing an object to be sealed on a portion of the adhesive surface of the second adhesive layer (X2). Step (2): A step for covering the object to be sealed and the adhesive surface of the second adhesive layer (X2) with a sealant, and then letting said sealant to cure so as to obtain a cured sealant. Step (3): A step for causing the expandable particles to expand so as to separate the hard support body and the first adhesive layer (X1) from each other at an interface P therebetween.
