An absorbent article comprising a liquid-permeable layer, a liquid-impermeable layer and an absorbent body situated between the liquid-permeable layer and liquid-impermeable layer, wherein the liquid-permeable layer has a first layer with a skin contact surface and a non-skin-contacting surface and a second layer situated on the non-skin-contacting surface side of the first layer, the second layer is a layer formed by heat shrinkage of a heat-shrinkable fiber layer and the first layer is a layer formed by deformation of a heat-extendable fiber layer, which is partially joined to the heat-shrinkable fiber layer by a joining section, by heat shrinkage of the heat-shrinkable fiber layer and heat stretching of the heat-extendable fiber layer, a projection bulging out on the skin contact surface, produced by deformation of the heat-extendable fiber layer, is formed at least in an excretory opening contact region on the skin contact surface, and at least the projection of the excretory opening contact region is coated with a coating consisting essentially of a blood slipping agent having at 40° C. a kinematic viscosity of 0.01 to 80 mm2/s at, a water holding percentage of 0.01 to 4.0 mass %, and a weight-average molecular weight of less than 1,000, and the coating is configured to slip down from the skin contact surface, through the liquid-permeable layer to the absorbent body along with menstrual blood.
