<P>PROBLEM TO BE SOLVED: To provide a sheet hardly causing a core mark and blocking, a roll-like sheet, and a winding method. <P>SOLUTION: This sheet 10 is wound around a winding core 100, wherein, in a cross-section in the thickness direction t of the sheet 10, at a winding-start sheet end 11 in the longitudinal direction S of the sheet 10, a front edge part 15 of a surface 14 on the back side becoming the winding core 100 side is located on the side in a winding direction S1 in which the sheet 10 is wound around the winding core 100 relative to a front edge part 13 of a surface 12 on the top side being the side opposite to the winding core 100 side. The sheet 10 is composed by sequentially laminating a base material sheet 20, an adhesive layer 30 and a separation sheet 40. An angle θ formed between a side face of the sheet end 11 and the surface 14 on the back side is in the range of 95° to 175°. This roll-like sheet 150 includes the sheet 10 and the winding core 100 around which the sheet 10 is wound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
