Claim:
1. An absorbent article comprising: a first liquid-permeable layer, a liquid-impermeable layer, a second liquid-permeable layer, an absorbent core disposed between the first liquid-permeable layer and the liquid-impermeable layer, and a joint section joining the first liquid-permeable layer and the absorbent core, wherein the absorbent core includes absorbent materials having a hydrophilic fiber and a superabsorbent polymer, wherein the absorbent core has a first region having a predetermined absorbent material basis weight and a second region having a predetermined absorbent material basis weight which is lower than that of the first region, wherein a ratio of a superabsorbent polymer basis weight to the predetermined absorbent material basis weight in the second region is from 10/100 to 47/100, wherein the joint section is formed inside the second region, wherein the second liquid-permeable layer is not joined with the absorbent core by the joint section, and wherein the ratio of the superabsorbent polymer basis weight to the predetermined absorbent material basis weight in the second region is 23/100 to 92/100 times a ratio of the superabsorbent polymer basis weight to the predetermined absorbent material basis weight in the first region.
