<P>PROBLEM TO BE SOLVED: To provide a sheet product that has excellent yield and has excellent workability in use. <P>SOLUTION: The sheet product includes a pressure-sensitive adhesive sheet which has pressure-sensitive adhesiveness and is in the form of a sheet, a base separator which is disposed on one surface of the pressure-sensitive adhesive sheet so that the separator can be released from the pressure-sensitive adhesive sheet and which supports the pressure-sensitive adhesive sheet and serves as a base, and a protective separator which is disposed on the other surface of the pressure-sensitive adhesive sheet so that the separator can be released from the pressure-sensitive adhesive sheet. The peel force between the pressure-sensitive adhesive sheet and the base separator is less than the peel force between the pressure-sensitive adhesive sheet and the protective separator and is 0.05-0.8 N/50 mm. The pressure-sensitive adhesive sheet and the protective separator are notched in the thickness direction of the pressure-sensitive adhesive sheet so that the pressure-sensitive adhesive sheet and the protective separator can be released, in the state of being superposed on each other, as separate pieces from the base separator. The base separator has a thickness of 60 μm or more. The surfaces of the base separator and the protective separator has a surface roughness Ra of 3 μm or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
