In a method for manufacturing paper or the like, in which cationic polymer microparticles comprised of polyacrylamide and a fine-particle inorganic component are added to the paper pulp following the final shearing step and prior to the headbox, whereupon the paper pulp is subjected to dehydration while forming sheets, followed by sheet drying, a polymer mixture comprising a linear cationic polymer and a linear anionic copolymer, whose overall ionicity is anionic, is additionally added immediately prior to the headbox. |
