Method of separating plates

Abstract

It is an object of the present invention to provide a method that can separate two plates laminated via a pressure-sensitive adhesive sheet, smoothly, efficiently, and accurately without such force (load) that large strain (deformation) leading to breakage or cracking occurs being substantially applied to the plates. The method of separating plates according to the present invention is a method of separating two plates laminated via a double-sided pressure-sensitive adhesive sheet, comprising placing a cutting tool having a cutting edge angle of not more than 25° and a thickness of not more than 20 mm, on a side of a structure composed of a double-sided pressure-sensitive adhesive sheet and two plates, between the double-sided pressure-sensitive adhesive sheet and the plate, and applying force in a normal direction of the plate.
