Disclosed is a tissue paper manufactured so as to be bulky without using bulking agents and the like and without increasing the number of manufacturing processes. Also disclosed is a method of manufacturing secondary whole rolls for a tissue paper product, which comprises (1) a laminating step of forming a laminated continuous sheet by laminating primary whole rolls fed from a plurality of primary whole rolls in a direction along which the rolls continue; (2) a chemical-solution applying step of applying chemical solution only to one of the top layers of the laminated continuous sheet or applying more chemical solution to one of the top layers than to the other top layer; (3) a joining step of forming linear joint portions that prevent layer separation on the laminated continuous sheet by nipping the laminated continuous sheet between a receiving roller and a driven roller. (4) a slitting step of slitting the laminated continuous sheet into sheets having a width or a several-fold width of a tissue paper product; and (5) a coiling step of forming a plurality of secondary whole rolls having the width or the several-fold width of the tissue paper product by coaxially coiling the slit laminated continuous sheets. |
