Abstract
An adhesive sheet 301A having a predetermined form is laminated onto a long release sheet 2A, and a protective member 5A which is thicker than the adhesive sheet 301A is provided in a position so as not to overlap the adhesive sheet 301A when a laminate sheet 1A is wound into a roll. According to this laminate sheet 1A, defects can be prevented from forming on the adhesive sheet 301A when the laminate sheet 1A is wound into a roll.
