Document Type and Number:
WIPO Patent Application WO/2018/181511
Kind Code:
A1
Abstract:
The present invention pertains to an adhesive sheet 1 delamination method for delaminating the adhesive sheet 1 provided with at least an adhesive layer 2 and delaminating attaching bodies W, W' attached to the adhesive surface P of the adhesive layer 2, wherein the method is characterized in that: the adhesive layer 2 has an air chamber 3 therein; and a depressurizing process for expanding a gas inside the air chamber 3 is performed on the adhesive sheet 1, to which at least the attaching bodies W, W' are attached, to thereby reduce the adhesion of the adhesive layer 2 and delaminate the adhesive sheet 1 and the attaching bodies W, W'. Through this method, the adhesion can be reduced at a desired timing by means of a novel acting mechanism.
