Abstract
A non-adhesive coated area substantially accurately coinciding with the width of a blade is formed on an adhesive sheet fabricated by forming the adhesive layer by coating an adhesive on the entire one side surface of a release sheet, scraping the adhesive layer by a blade having a suitable width to form a non-coated area in the adhesive layer, and then bonding a surface sheet to the adhesive layer having the non-coated area.
