Provided is an underpants-type wearable article for adults which is provided with a relatively slim liquid-absorbing core, is capable of temporarily diffusing and retaining a body fluid in an amount equal to or greater than the water-retention amount of the liquid-absorbing core, and is capable of being worn by women without any sensation of resistance. A first dimension (L1) from the lower end edge (14a) to the upper end edge (14b) of a front waist panel (14) in a non-extended state is smaller than a second dimension (L2) from the lower end edge (14a) to the lower end edge of an absorption panel (16). The sum total of the first dimension (L1) and the second dimension (L2) is 250-290 mm. A fourth dimension (L4) of one of a pair of non-overlapped sections of the lower end edge (14a) in the horizontal direction (X), said non-overlapped sections being positioned outside in the horizontal direction (X) with respect to a section of the lower end edge (14a) which overlaps the absorption panel (16), is 45-80% the size of a third dimension (L3) in the horizontal direction (X) of the section of the lower end edge (14a) which overlaps the absorption panel (16). The water-retention amount of an absorbent body is 150-400 g. The extensional stress in an expansion/contraction region in which front waist elastic bodies (20) are disposed is higher than the extensional stress in an expansion/contraction region in which rear waist elastic bodies (23) are disposed.本發明之目的係在於提供一種大人用短褲型穿著用物品，其具備有較纖細的吸液性芯材，並且可暫時地擴散、保持吸液性芯材的保水量以上之體液，可使女性不會感到抵抗感而穿用。用以解決問題之手段為，在紙尿布(10)的非伸長狀態，從前腰圍薄片體(14)的下端緣(14a)到上端緣(14b)之長度尺寸亦即第1尺寸(L1)係較從前腰圍薄片體(14)的下端緣(14a)到吸收薄片體(16)的下端緣之長度尺寸亦即第2尺寸(L2)小，第1尺寸(L1)與第2尺寸(L2)的合計尺寸為250~290mm。又，對於前腰圍薄片體(14)的下端緣(14a)之與吸收薄片體(16)重疊的部分之橫方向(X)的長度尺寸亦即第3尺寸(L3)，第4尺寸(L4)為45~80%的大小，第4尺寸係位於下端緣(14a)中之重疊部分的橫方向(X)外側之一對非重疊部分中的其中一方之非重疊部分的橫方向(X)之尺寸，吸收體的保水量為150~400g，在前腰圍區域(11)中配置有朝橫方向(X)延伸的前腰圍彈性體(20)之伸縮區域的伸長應力係較在後腰圍區域(12)中配置有朝橫方向(X)延伸的後腰圍彈性體(23)之伸縮區域的伸長應力高。
