  • Patent number: 11931232
    Abstract: To enable an absorbent article to fit easily around the legs when worn and to improve fit. A pad which includes a polymer sheet having a superabsorbent polymer disposed between two nonwoven fabric sheets. Planar-shaped linear embossed grooves that protrude inward in a width direction from each side edge are formed at positions of the polymer sheet on which the groin of a wearer abuts when worn. Standing gathers that rise along a longitudinal direction on a skin side are formed on both side portions on the skin side. Regions that are surrounded by the embossed grooves tend to deform around the legs with the embossed grooves as flexible shafts, so that the polymer sheet fits easily around the legs when worn and fit is improved.
