摘要:
An absorbent article is provided with a liquid-permeable top sheet, a liquid-impermeable back sheet and an absorbent body between the top sheet and the back sheet. The top sheet has a non-woven fabric having multiple convex portions and multiple concave portions. The individual convex portions and concave portions contain a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm2/s at 40° C., a water retention rate of 0.01-4.0 mass % and a weight-average molecular weight of less than 1,000. The amount of the blood lubricity-imparting agent at the top of the convex portions is larger than in the parts other than the top of the convex portions. The amount of the blood lubricity-imparting agent at the bottom of the concave portions is larger than in the parts other than the bottom of the concave portions.
