Provided is a method of reusably separating two adhered plates, including step 1 for firmly adhering two plates adhered to each other via a pressure-sensitive adhesive sheet or a curable resin layer to a first jig and a second jig, respectively, step 2 for detaching the two plates by moving at least one of the first jig and the second jig to produce a shear stress causing breakage of the pressure-sensitive adhesive sheet or the curable resin layer, and step 3 for removing the two plates after detachment from the jigs, wherein, in the aforementioned step 1, one or both of the plates is(are) firmly adhered to the jig(s) via a silicone pressure-sensitive adhesive sheet or porous pressure-sensitive is adhesive sheet. Using the method, two plates adhered to each other via a pressure-sensitive adhesive sheet or a curable resin layer can be stably and reusably detached by certainly fixing them by using jig fixtures. |
