PROBLEM TO BE SOLVED: To provide an absorbent article 1 or the like superior in transfer of a liquid to an absorber 3 of a nonwoven fabric sheet 11 provided on a surface side of the absorber 3.SOLUTION: An absorbent article 1 has a nonwoven fabric sheet 11 provided on a surface side of an absorber 3 absorbing a liquid. A reverse-side average value Ab obtained by projecting a range extending over 220 &mum in the thickness direction from the reverse 11b of the nonwoven fabric sheet 11 on the plane whose normal direction is the thickness direction and averaging the total area of interfiber clearances by the total number of clearances corresponding to the total area is lower than a surface-side average value As obtained by projecting a range extending over 220 &mum in the thickness direction from the surface 11s of the nonwoven fabric sheet 11 on the plane whose normal direction is the thickness direction and averaging the total area of the projected interfiber clearances by the total number of clearances corresponding to the total area. The average value As of the surface side is equal to or larger than 902 (&mumper piece) and the average value Ab of the reverse side is equal to or larger than 392 (&mumper piece).
