A second elasticized region is defined adjacent the first elasticized region so as to extend in the transverse direction Y, and a pair of third elasticized regions are defined adjacent the second elasticized region and spaced from and opposed to in the transverse direction Y on both sides of a non-elasticized region formed in a transverse middle of the front waist region. The second elasticized region extends across the front flap of the absorbent chassis.
