Abstract
The absorbent article has an outer sheet that provides an outer surface of the absorbent article, an inner sheet disposed on the inner side of the outer sheet, and elastic members for making below-waist gathers disposed between the two sheets. A patterned sheet is disposed between the outer and inner sheets such that the pattern of the patterned sheet may be seen through the outer sheet from the outside of the diaper. The elastic members for below-waist gathers each have a portion contributory to elastic extensibility and contractibility in the regions outside the lateral sides of the patterned sheet and a portion substantially non-contributory to elastic extensibility and contractibility in the region inside the lateral sides of the patterned sheet. The latter portion of the elastic member is disposed between the patterned sheet and the inner sheet and preferably is kept out of sight from the outside.
