Abstract
An absorbent article, in which an erroneous impression of replacement time is not given to a wearer, includes an absorbent body, a front sheet covering the absorbent body, and a rear sheet, a pair of masking members being disposed along a longitudinal direction of the absorbent body, close to two ends of a short direction of the absorbent body, the masking members being of porous film having pores continuous in the direction of thickness, the thickness thereof preferably being 0.4 mm or greater under a load of 20 g/cm2. By this means, seepage of fluid at the side margins of the front sheet is deferred and misunderstanding of replacement time by the wearer is prevented.
