An absorbent article 1 includes an absorbent body 3 and an outer cover 2. The outer cover 2 has a front section A, crotch section C, and a rear section B and includes an outer sheet 21, an inner sheet 22, and elastic members 23. The outer cover 2 has a below-waist gather formed of a composite stretch panel in its below-waist portion D. The composite stretch panel has the outer and inner sheets 21, 22 bonded at bonds discretely arranged in the stretch direction thereof and the direction perpendicular thereto. The elastic members 23 extend not to pass the bonds without being fixed to the outer and inner sheets 21, 22 at other than their both ends. The outer and inner sheets 21, 22 form folds continuously extending over a plurality of the elastic members 23. The waist portion F of the outer cover 2 has a lower extension percentage in its laterally middle part than in the other parts on both sides of the middle part.本發明係關於吸收性物品(1),其包含吸收性本體(3)與外包材(2);外包材(2)具有腹側部(A)、股下部(C)以及背側部(B)。外包材(2)包含外層薄片(21)、內層薄片(22)以及彈性構件(23);於外包材(2)之腰圍部(D)設置有由複合伸縮部所形成之腰圍部皺褶。於複合伸縮部中,於伸縮方向以及與該伸縮方向的正交方向上,藉由間斷的接合部將外層與內層薄片(21、22)接合。彈性構件(23)係以不通過上述接合部之方式而配置,並且在除了兩端部以外之部分中並不固定於外層薄片(21)及內層薄片(22)上。外層及內層薄片(21、22)形成複數條褶,其中複數個褶一直連續延伸至於數條彈性構件(23)。腰部(F)之位在外包材(2)的寬度方向中央部之位置的伸長率小於位在外包材(2)的寬度方向外側部之位置的伸長率。1、1A...短褲型拋棄式尿褲2...外包材3...吸收性本體11...側密封部12...腰部開口部13...腿部開口部21...外層薄片A...腹側部C...股下部G1...腰圍部皺褶G2...腰部皺褶G3...腿部皺褶G4...前股皺褶
