Abstract
A disposable diaper has a covering member adapted to cover a wearer's crotch and waist regions. The covering member includes an elastically stretchable first layer and an inelastically stretchable second layer formed with a plurality of continuous fibers. The continuous fibers are fixed to the first layer in at least two bonding zones. The covering member presents a particularly large value of L/D, a ratio of a length L of each continuous fiber and a distance D in straight line between each pair of the adjacent bonding zones.
