Method of detaching plates
Disclosed is a method for detaching two plates bonded through a double-coated pressure-sensitive adhesive sheet without substantially applying such a force (load) to the plates as to cause large distortion (deformation) leading to fracture or breakage of the plates. The method detaches two plates bonded through a double-coated pressure-sensitive adhesive sheet by applying a force to at least one of the two plates at least in a direction normal to the plate at such a temperature that the double-coated pressure-sensitive adhesive sheet has a storage elastic modulus of 1.0×107 Pa or more as measured by dynamic viscoelastic measurement.
