Abstract
A sanitary napkin includes a napkin body having a liquid-absorbent layer for absorbing and retaining liquid and a projection projecting from a body surface of the napkin body. The projection is secured at laterally spaced base ends to the body surface of the napkin body. A distance between the base ends varies longitudinally of the projection. A height of the projection from the body surface of the napkin body decreases with increasing the distance between the base ends.
