摘要： An absorbent article (1) that comprises an absorbent body (10) and exterior members (30, 40) provided on the non-skin side of the absorbent body (10), wherein the exterior members (30, 40) include hydrophilic non-woven fabric parts (32, 42) on at least a part of the most non-skin side surface. The hydrophilic non-woven fabric parts (32, 42) are disposed so that a value, which is calculated by dividing the difference between the weight of the absorbent article (1) when the packaged absorbent article (1) is opened and the weight of the absorbent article (1) in a dried state by the weight of the absorbent article (1) in the dried state, is 0.1 or less.

摘要： An underpants-type absorbent article (1) that comprises an absorbent body (10) and a waist line member (20) consisting of a front waistline portion (20) and a back waistline portion (30), said front waistline portion (20) and said back waistline portion (30) being annularly joined together by a pair of side joint portions (50) disposed on both sides in the horizontal direction, and that is provided with a pair of leg holes (LH). In the waistline member (20), hydrophilic regions (32, 42) are disposed on the most non-skin side of at least a part of the regions overlapping the pair of side joint portions (50) in the vertical direction. In the regions along the leg holes (LH), hydrophobic regions (13b, 31, 41), which are less hydrophilic than the hydrophilic regions (32, 42), are disposed on the most non-skin side of at least the parts located at the bottom (CL).
