Abstract

[Problem] To improve retainability of super-absorbent polymer particles in a hardwood pulp fiber-containing absorbent body. [Solution] The problem described above can be solved by an absorbent article including an absorbent element 50 having an absorbent body 56 and a wrapping sheet 58 that wraps the absorbent body 56, wherein the absorbent body 56 is made of mixing and aggregating pulp fibers and super-absorbent polymer particles, a percentage of particles of which a pre-swelling particle diameter is smaller than an average fiber length of hardwood pulp fibers in super-absorbent polymer particles 56p is 60% by mass or more, the absorbent element 50 is provided with a plurality of spaced high-compression portions 51 that are compressed in a thickness direction TD so as to be recessed into the absorbent body 56 from a surface of the absorbent element 50, portions other than the high-compression portions 51 in an arrangement region of the plurality of high-compression portions 51 are non-high-compression portions 52 that are thicker and lower in density than the high-compression portions 51, a shortest distance from each of the plurality of high-compression portions 51 to the closest other high-compression portion 51 is 1 to 4 mm, and an area of each of the high-compression portions 51 is 2 to 200 mm<2>.
