A method for producing paper, which comprises a step wherein at least one of a paper base material and a compound (A) that is selected from among compounds that have a carbon-carbon unsaturated bond, while containing no fluorine atom in the molecular structure and compounds that generate radicals when irradiated with an electron beam, while containing no fluorine atom in the molecular structure, is irradiated with at least one of ionizing radiation and a plasma, thereby introducing a layer that is formed of the compound (A) into the surface of the paper base material.
