- 摘要：
PROBLEM TO BE SOLVED: To provide low-diffusivity permeable paper which exhibits a low liquid diffusivity and a high liquid permeation when it is used for an absorbent article and to provide the absorbent article using it.
SOLUTION: The low-diffusivity permeable paper for absorbent articles is obtained by a wet paper making method. The average pore diameter by pore diameter distribution measurement of the low-diffusivity permeable paper is 30 &mum or more. In addition, the pore superficial area in a region of pores whose diameter is 0.7-1.3 times as large as the average pore diameter occupies 70% or more of the whole pore superficial area of the low-diffusivity permeable paper. In addition, the pore superficial area in a region of pores whose diameter is 20 &mum or less occupies 10% or less of the whole pore superficial area of the low-diffusivity permeable paper. Preferably, the low-diffusivity permeable paper includes hydrophilic fibers and is treated by a sizing agent. Also, the absorbent article 10 is provided with the low-diffusivity permeable paper 1 between a surface sheet 11 and an absorber 13.
