PROBLEM TO BE SOLVED: To improve air permeability of a sheet adopted in a flute structure.SOLUTION: In a disposable diaper, at least either on a front body section or a back body section, a cushion part 40 is formed. In the cushion part 40, waist stretchable members 43 are fixed between an inner sheet 41 and an outer sheet 42 in the state that they are stretched along a width direction of the diaper. In the cushion part 40, cushion formation sheets 44 are put on the inner sheet 41 and/or the outer sheet 42 and are intermittently joined in the way that a joint part 51 and a non-joint part 52 follow each other by turns in the width direction. In the cushion formation sheets 44, a plurality of open holes 60 or recesses classified into a row group and a column group are formed. Joint straight lines joining the plurality of open holes 60 or recesses belonging to the column group are tilted at a prescribed angle with respect to a reference straight line extending along a longitudinal direction.SELECTED DRAWING: Figure 5 |
