ABSTRACT:
A sanitary napkin includes a liquid-permeable topsheet, a backsheet, and a liquid-absorbent layer disposed between the topsheet and the backsheet. The liquid-absorbent layer has a vagina-facing region on a longitudinal centerline of the sanitary napkin and side regions on both sides of the vagina-facing region. The liquid-absorbent layer has a greater thickness and a greater bending stiffness in the vagina-facing region than in the side regions to provide hinge lines along boundaries between the vagina-facing region and the side regions.
