The disposable diaper includes: a pair of three-dimensional gather sheets provided oppositely to each other; and an absorber interposed between the back sheet and the top sheet, and having liquid absorbability. The second sheet material having the liquid impermeability of each three-dimensional gather sheet is joined with the back sheet in a side flap part. |
