PROBLEM TO BE SOLVED: To provide a disposable diaper with a flexible texture on touch while it is lightweight and rich in cushioning properties.SOLUTION: In the disposable diaper, a liquid impermeable sheet 11, as shown in Figure 7, has a surface on which a number of openings of recessed parts 14 are arranged by certain intervals and a back surface on which a number of projecting parts of the recessed parts 14 are arranged by certain intervals by arranging a number of cup-shaped recessed parts 14 recessed from the surface to the back surface by intervals. A packaging sheet 58 forming the bottom face of an absorbing element 50 is not joined with the recessed parts 14 of the surface of the liquid impermeable sheet 11 but is joined with the parts except the recessed parts 14 of the surface by joining parts 81, and the insides of the recessed parts 14 of the surface are made to be spaces 83, and the inner face of the sheathing sheet 12 is not joined with the spaces among the projecting parts of the recessed parts 14 of the back surface of the liquid impermeable sheet 11, but is joined with the bottom parts 14b of the recessed parts 14 of the back surface by joining parts 82, and the spaces among the projecting parts of the recessed parts 14 of the back surface are made to be spaces 84.COPYRIGHT: (C)2012,JPO&INPIT【課題】軽量で、クッション性に富むものでありながら、柔軟な風合いを有する使い捨ておむつを提供する。【解決手段】上記課題は、液不透過性シート11は、図7にも示すように表側から裏側へ窪むカップ状の凹部14が間隔を空けて多数配列されることにより、凹部14の開口が間隔を空けて多数配列された表面と、凹部14の突出部分が間隔を空けて多数配列された裏面とを有しており、吸収要素50の底面を形成する包装シート58は、液不透過性シート11の表面の凹部14とは接合されずに当該表面の凹部14以外の部分と接合部81により接合されて、表面の凹部14内は空間83とされ、外装シート12の内面は、液不透過性シート11の裏面における凹部14の突出部分間とは接合されずに、当該裏面における凹部14の底部14bと接合部82により接合されて、裏面の凹部14の突出部分間は空間84とされている、使い捨ておむつにより解決される。【選択図】図3
