Abstract
A method of producing an underpants-type disposable diaper includes forming an outer member having a non-stretchable region disposed in an intermediate region in the width direction and stretchable regions disposed on the two sides of the non-stretchable region in the width direction by: fixing elastic members to an inner sheet layer and an outer sheet layer in at least two edge portions of portions to be the stretchable regions without fixing the elastic members to the inner sheet layer nor the outer sheet layer in a portion to be the non-stretchable region; disposing a graphic sheet and disposing a no-extra-sheet region between the inner sheet layer and the outer sheet layer in the side portion of the non-stretchable region; cutting the elastic members and leaving cut marks and idle elastic members over the no-extra-sheet region; and leaving the elastic members in a region overlapping with the graphic sheet uncut.
