The top sheet has protrusions and indentations in the thickness direction. The basic weight of the protrusions is greater than the basic weight of the indentations. The color difference between the Lab value of the color of the colored element visible through the protrusions of the top sheet and the Lab value of the color of the colored element visible through the indentations of the top sheet is 2.8 or more.

Absorbent article and disposable diaper having viewed-through top sheet

An absorbent article includes a rear waist region provided with a waist region elastic member attached thereto under tension. The waist region elastic member is formed with a plurality of slits each extending in a longitudinal direction and extending through the elastic member in a thickness direction thereof. The waist region elastic member is stretched in a transverse direction as the diaper is put on the wearer's body and thereupon the slits are opened up to form respective through-holes. A first graphics display region formed in combination with the slits includes note stems and note tails. Each of these note stems is contiguous to the associated through-holes. In the area nearer a crotch region than the first graphics display region, a second graphics display region is formed. The first and second graphics display regions cooperate to each other.
