Absorbent article

An absorbent article comprising:

• a liquid-permeable top sheet;
• a liquid-impermeable back sheet;
• and
• an absorber provided between the top sheet and the back sheet, wherein
• the absorbent article has a predetermined length in a front-to-rear direction, and a predetermined width in a width direction perpendicular to the front-to-rear direction,
• the absorber includes a first absorber layer located at a position closer to the top sheet than to the back sheet, a second absorber layer located at a position closer to the back sheet than to the top sheet, and a groove or a slit formed in the first absorber layer and extending in the front-to-rear direction,
• the first absorber layer includes
• a high-stiffness part, made of an absorbent material, and extending outward in the width direction from an edge portion of the groove or slit, and
• a low-stiffness part, made of an absorbent material, having a stiffness lower than a stiffness of the high-stiffness part, and provided on an outer side of the high-stiffness part in the width direction,
• an entirety of the first absorber layer, including the high-stiffness part and the low-stiffness part, overlaps the second absorber layer in a top view, and
• the stiffness of the high-stiffness part is higher than a stiffness of the second absorber layer.
