Abstract
Disclosed is a sanitary napkin which is effective in preventing liquid from leaking out obliquely rearward. The sanitary napkin has rear flaps rearward of fold-back flaps to be wrapped around a crotch part of an undergarment. The rear flap has a side edge substantially parallel to a longitudinal centerline. The rear flap is provided at its front portion with a rear pressure-sensitive adhesive layer. The rear pressure-sensitive adhesive layer is disposed forward of a rear end of a leakage preventing wall and a rear end of a main absorbent region. Since the rear flaps can be firmly fixed through the rear pressure-sensitive adhesive layers, the leakage preventing walls hardly move, so that the leakage preventing walls, as well as the rear flaps outside them, can effectively prevent obliquely rearward leakage.
