In this pants-type absorbent article (1), an absorbent main body (10) is provided with an absorbent body (12), leg members (15) provided with a leg elastic member (61) and defining a leg opening (LH), and a sheet member (14) on a non-skin side of the absorbent body (12), and waist parts (20, 30) are provided with waist elastic members (22, 32). The sheet member (14) has, at lateral end parts thereof, a plurality of adhered regions (62) at which the sheet member (14) and the leg members (15) are adhered. The adhered regions (62) have a predetermined length (L1) in the lateral direction. When the leg members (15) are stretched, in a front lower part (FU) that is located in front of and below the leg openings (LH) in a worn state, there is at least one adhered region (62) that is inclined so that the end on the leg opening (LH) side of the adhered region (62) is positioned above the end on the absorbent body (10) side.[課題]目的在使短褲型吸收性物品的腿圍開口部的貼合性提升。 [解決手段]吸收性本體(10)具備：吸收體(12)與腿圍彈性構件(61)，並具備：區劃腿圍開口部(LH)的腿圍構件(15)、與位在吸收體(12)的非肌膚側的薄片構件(14)，腰圍部(20、30)具備腰圍彈性構件(22、32)之短褲型吸收性物品(1)，其中，在薄片構件(14)的左右方向的端部具有熔接薄片構件(14)與腿圍構件(15)的複數個熔接區域(62)，熔接區域(62)在左右方向具有預定長度(L1)，在穿用狀態中的腿圍開口部(LH)的前側且位於下側的前下側部分(FU)至少設置1個將腿圍構件(15)伸長的狀態下，使熔接區域(62)的腿圍開口部(LH)之側的端較吸收體(10)之側的端更朝上側傾斜的熔接區域(62)。
