(57) ABSTRACT
An absorbent article such as sanitary napkin having an absorbent laminate is provided on a skin-noncontactable side ol the laminate with deformation inducing means. The deformation inducing means include a hydrophobic panel member and an elastically stretchable member adapted to pull the panel member toward its middle under contractile force ol the elastically stretchable member and thereby to convexly deform the panel member toward a skincontactable side ol the laminate. Convex deformation ol the panel member by the deformation inducing means allows the laminate to be convexly deformed.
