Abstract
A laminate is produced in which a long release sheetA, an adhesive layerA and a base materialA are laminated together, and the base materialA and the adhesive layerA are cut (half cut) so as not to penetrate through the release sheetA, so as to divide the base materialA and the adhesive layerA into cover sheet portionsA, bolstering portionsA and a remainder portionA. The remainder portionA is then peeled off and removed, and an outer end portion of each of the bolstering portionsA is half cut so as not to penetrate through the release sheetA, raised portionsA being formed through the half cutting. The laminate sheet can be produced at low cost, and defects can be prevented from being formed on the adhesive sheet when the laminate sheet is wound into a roll.
