In a pants-type disposable diaper, an outer covering sheet formed of a nonwoven fabric has front and back parts to be positioned on front and back sides of a wearer, and a middle part lying between the both. An absorbent body is attached on the outer covering sheet so as to lie from the front part to the back part, to absorb excrement from the wearer. Sheet members are bonded on the front and back parts, and each end portion of the absorbent body is positioned and fixed between the sheet member and the outer covering sheet. In the disposable diaper, since the sheet member is a laminated sheet of plastic film and nonwoven fabric, stretching of the sheet member is suppressed and it is possible to easily bring the absorbent body in close contact with the crotch region of the wearer when putting the disposable diaper on the wearer.可丟棄尿布(1)係在上端具有身體部開口且在下部具有一對腿部開口的褲型,由不織布形成的外包裝薄片(4)係具有:包覆戴用者的前側的前方部(401)及包覆後側的後方部(403)、以及前方部(401)與後方部(403)之間的中間部(402)。在外包裝薄片(4)上,由前方部(401)遍及後方部(403)被安裝有吸收體(20),以吸收由戴用者而來的排泄物。在前方部(401)及後方部(403)的各個被接合薄片構件(5),吸收體(20)的各端部被夾在薄片構件(5)與外包裝薄片(4)之間而予以固定。在可丟棄尿布(1)中,薄片構件(5)被形成為塑膠膜與不織布的層積體,藉此抑制片構件(5)伸張,可在裝設時輕易地使吸收體(20)與戴用者的大腿間部相密接。1...可丟棄尿布5...薄片構件11...身體部開口12...腿部開口401...前方部402...中間部403...後方部
