Abstract

An absorbent article which can make a wearer sight a changed design particularly at a diaper change. A waist elastic element (3) is set on a diaper (1) in a stretched state in a rear waist region (6) of the diaper (1), and the elastic element (3) is provided with plural slits (16) which run in the longitudinal direction (Y) and pass through in the thicknesswise direction. When the diaper (1) is worn, the waist elastic element (3) is stretched, so that the slits (16) form openings (27). In a first design area (23) present on the periphery of the slits (16), stems and tails are so printed as to fit the slits (16). When the slits (16) are widened to form the openings (27), the openings (27) are recognized as heads to form notes. In an area spread from the first design area (23) to a crotch region (7), a second design area (24) is formed and a picture of an instrument-playing character is printed in the area (24). Thus, the diaper can make a wearer feel as if the notes appearing in the first design area (23) came from the instrument.
