PROBLEM TO BE SOLVED: To improve a degree of design freedom of an inner-body outer sheet.SOLUTION: A disposable diaper includes: a belly-side outer sheet 12F a back-side outer sheet 12B an inner body 200 provided thereover and incorporating an absorber 56 for absorbing excreta, where the belly-side outer sheet 12F and the back-side outer sheet 12B are not connected at a crotch side and an inner-body outer sheet 12M for covering the back face of the inner body 200 at least in a separation area. When the disposable diaper is manufactured, a prescribed width of belt-like outer sheet 12 material 12S is divided into three, two of them are used for forming a part to become the belly-side outer sheet 12F and a part to become the back-side outer sheet 12B, and the residual one is used for a part to become the inner-body outer sheet 12M. The part to become the inner-body outer sheet 12M is cut at prescribed intervals apart to form individual inner-body outer sheets 12M, and then, the individual inner-body outer sheets 12M are intermittently stuck to the back side of the part to become the inner body 200.COPYRIGHT: (C)2014,JPO&INPIT【課題】内装体用外装シートの設計の自由度を向上させる。【解決手段】腹側外装シート12Fと、背側外装シート12Bと、これらにわたり設けられた、排泄物を吸収する吸収体56を内蔵する内装体200とを備え、腹側外装シート12F及び背側外装シート12Bが股間側で連続しておらず、少なくともこの離間領域における内装体200の裏面を覆う内装体用外装シート12Mを備えた使い捨ておむつを製造するにあたり、所定幅の帯状外装シート12素材12Sを三分割し、そのうちの二本を用いて腹側外装シート12Fとなる部分及び背側外装シート12Bとなる部分を形成し、残りの一本は内装体用外装シート12Mとなる部分とする。この内装体用外装シート12Mとなる部分を所定の間隔を空けて切断して個々の内装体用外装シート12Mを形成した後、前記内装体200となる部分の裏面に個々の内装体用外装シート12Mを間欠的に貼り付ける。【選択図】図3
