[PROBLEMS] To increase the desired touch (texture) and moisturizing properties while reducing the amount of chemicals applied by preventing the sheet from growing, reducing the weight of the paper, and reducing the paper stiffness. A household sanitary thin paper exhibiting the characteristics of SOLUTION: In an inter folder, continuous sheets 10 and 20 are unwound from winding rolls 1 and 2 obtained by winding a base paper made of pulp fibers with a predetermined width, and are folded and stacked by a folding and stacking means 50. At that time, before the folding and stacking, the chemical solution is continuously applied by roll transfer by roll transfer devices 33, 34, 43, and 44 for transferring the chemical solution to the target sheet.
