Abstract
A disposable diaper is provided with a skin-contactable sheet piece above a liquid-pervious topsheet. The skin-contactable sheet piece is formed with openings extending in a back-and-forth direction through which body waste is guided toward the topsheet and both lateral zones of the sheet piece on both sides of these openings as viewed in a transverse direction are provided with elastic members attached under tension. Outside the skin-contactable sheet piece as viewed in the transverse direction, leak-barriers are provided and the lateral zones of the skin-contactable sheet piece are bonded to the leak-barriers along regions defined between proximal edges and free edges of the respective leak-barriers.
