Patent number: 11344455Abstract: An absorbent article comprising a polymer sheet 4 in which a super absorbent polymer 12 exists between an upper layer sheet 10 arranged on the skin side and a lower layer sheet 11 arranged on the non-skin side is included. A fiber absorber 5 including pulp fiber is disposed adjacent to the surface on the skin side of an area corresponding to a body fluid discharge region H of a wearer in the polymer sheet 4. The super absorbent polymer 12 is not arranged in an area which overlaps with the fiber absorber 5, and is arranged in the other area.
