Abstract

Provided is an absorbent article having a top sheet with an opening-formed area in which openings are formed, and non-opening-formed areas in which no openings are formed, said absorbent article being capable of preventing liquid from remaining on the surface of the opening-formed area of the top sheet. In the present invention, the top sheet is a resin sheet having an opening-formed area () in which openings are formed, and non-opening-formed areas () in which no openings are formed. The opening-formed area () is disposed in an outlet-facing area () that faces at least an outlet for fluid from a wearer. The top sheet () has a blood modifier layer on the surface of at least the outlet-facing area (). The blood modifier of the blood modifier layer has an inorganic/organic balance (IOB) of 0 to 0.60, a melting point of not more than 45° C., and an aqueous solubility of 0.05 g or less with respect to 100 g of water at 25° C.
