PROBLEM TO BE SOLVED: To provide a method of manufacturing a secondary base paper roll for tissue paper products which can prevent layers of a laminated continuous sheet to which a chemical is applied from causing separation and slippage. SOLUTION: The method of manufacturing a secondary base paper roll for tissue paper products includes a lamination process (51) to make primary continuous sheets S1 extended from a plurality of base paper rolls JR into a laminated sheet S2 in which the primary continuous sheets are laminated, a contact-embossing process (54) to provide a contact-embossing treatment to prevent interlayer separation and slippage to the laminated continuous sheet S2, a chemical application process (53) to apply a chemical to the laminated continuous sheet S2 after the contact-embossing process (54), a slitting process (55) to slit the laminated continuous sheet S2 to give it a product width of the tissue paper product or a multiple times larger width, and a winding process (56) to concentrically wind the slit laminated continuous sheet S2 and form a plurality of base paper rolls R having the product width of the tissue paper product or the multiple times larger width.
