Abstract

In an absorbent article, in which each of pressure-bonded parts has a linear shape extending in the length direction of the absorbent article, the pressure-bonded parts are formed with spacing at regular intervals in a discontinuous manner with respect to the length direction of the absorbent article and are also formed in multiple lines with spacing at regular intervals with respect to the width direction of the absorbent article, depressed parts are formed on a back-sheet-facing surface of an absorbent body that is located beneath the pressure-bonded parts, each of an excretory opening-contacting region in a top sheet and the pressure-bonded parts contains a blood lubricity-imparting agent having a kinematic viscosity of 0.01 to 80 mm/s at 40° C., a water hold percentage of 0.01 to 4.0 mass % and a weight average molecular weight of less than 1,000, and the amount of the blood lubricity-imparting agent in the pressure-bonded parts is larger than that in the excretory opening-contacting region.
