摘要:
Provided is an absorbent article including a top sheet that is excellent in maintaining shapes of the concaves and convexes and hardly causes a decrease in absorption rate.The above problem is solved by an absorbent article in which a plurality of dome-shaped convexes 31 protruding to a front surface side is arranged on a top sheet 22 including a nonwoven fabric, and grooves 32 are formed between adjacent convexes 31, characterized in that through-holes 80 penetrating the top sheet 22 in a thickness 22t direction are provided at intervals in a circumferential direction of each of the convexes 31, peripheral edge portions 81 of the through-holes 80 are high-density portions where constituent fibers of the nonwoven fabric are pushed to parts around the through-holes 80 from positions corresponding to the through-holes 80, a part of peripheral edges of the convexes 31 is formed by a part of the peripheral edge portions 81 of the through-holes 80, and a difference between a maximum value and a minimum value of an apparent thickness 22t is in a range of 0 to 50% of the maximum value in a portion of the top sheet 22 excluding the peripheral edge portions 81 of the through-holes 80.
