PURPOSE:To peel a sheet-shaped body off the surface of an adhesive layer without being restrained by a core after completing the manufacture of an adhesive roll by cutting off a bottom section of the sheet-shaped body. CONSTITUTION:The outer peripheral face of a body section 40 and a bottom section 41 of a sheet-shaped body 4 are disposed respectively along the inner peripheral face of a mold material 3 and a bottom section 31 of a mold, and at least the inner peripheral face of the body section 40 of said sheet-shaped body 4 is formed by a material of superior release properties. One end of a core 5 is formed integrally with the bottom section 41 on the center of the inside of the bottom section 41 of the sheet-shaped body 4 in a manner that the core 5 is concentric with the sheet-shaped body 4, and a space 100 to be able to store an adhesive material for forming an adhesive layer is formed between the inner peripheral face of the sheet-shaped body 4 and the outer periphery of the core 5. An area in the vicinity of the bottom section 41 of the sheet-shaped material 4 can be cut off after molding. |
