Abstract
A stripping method for stripping a support plate from a laminate including a substrate and the support plate adhered to the wafer via an adhesive layer, in which the adhesive layer is formed from an adhesive compound soluble in a non-polar solvent or a highly polar solvent; and the stripping method includes the step of supplying the non-polar solvent or the highly polar solvent, so that the non-polar solvent or the highly polar solvent is retained at least on an edge portion of that surface of the laminate which faces the support plate, and on a lateral surface of the laminate.
