Abstract

The present invention addresses the problem of in an absorbent article preventing the leakage of fiber constituting an absorbent core from a non coated region through a liquid permeable layer said leakage possibly occurring when the strength of the absorbent core is decreased due to liquid absorption. To solve this problem provided is a sanitary napkin (1) which comprises a top sheet (2) a back sheet (3) and an absorbent core (4) that is interposed between the top sheet (2) and the back sheet (3) wherein: the absorbent core (4) which involves a non coated region where the constituting fiber is exposed on the surface and in contact directly with the top sheet (2) contains a thermoplastic resin fiber said thermoplastic resin fiber containing as a monomer component an unsaturated carboxylic acid an unsaturated carboxylic acid anhydride or a mixture thereof at a mixing ratio by mass to a cellulose based water absorbing fiber of 1/9 or more; and the wet fiber fall off rate of the absorbent core (4) is controlled to 13.3% or less.
