Disclosed is a sheet product comprising: a pressure-sensitive adhesive sheet which has pressure-sensitive adhesiveness and is in the form of a sheet; a base separator which has been disposed on one surface of the pressure-sensitive adhesive sheet so that the separator can be removed from the pressure-sensitive adhesive sheet and which supports the pressure-sensitive adhesive sheet and serves as a base; and a protective separator which has been disposed on the other surface of the pressure-sensitive adhesive sheet so that the separator can be removed 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 have been incised in the thickness direction of the pressure-sensitive adhesive sheet so that the pressure-sensitive adhesive sheet and the protective separator can be removed, in the state of being superposed on each other, as separate pieces from the base separator. The base separator has a thickness of 60 [mu]m or more. The surfaces of the base separator and protective separator which face the pressure-sensitive-adhesive sheet each has a surface roughness Ra of 3 [mu]m or less.
