Abstract

An absorbent article includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body between the top and back sheets. The top sheet has first and second areas, each of which includes a blood lubricity-imparting agent that has a kinematic viscosity of 0.01-80 mm/s at 40° C., a water hold percentage of 0.01-4.0 mass %, and a weight average molecular weight of less than 1,000. The first area overlaps at least partially with an excretory orifice contact area of the top sheet that is configured to contact with the excretory orifice of the wearer. The second area is arranged more to a rear side in a lengthwise direction of the absorbent article than is the first area. A basis weight of the blood lubricity-imparting agent in the first area is higher than that of the blood lubricity-imparting agent in the second area.
