Abstract
A sanitary napkin includes a top layer having an upper layer made of a perforated thermoplastic synthetic resinous film and a lower layer made of thermoplastic synthetic fibers having a hydrophilic property higher than that of the upper layer. These upper and lower layers are intermittently heat sealed together except at a central zone of the napkin by thermally debossing the upper and lower layers so that the central zone may be thicker and softer than the remaining zone.
