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 has an apex and a pair of side wall portions formed of a liquid-permeable material. The apex is spaced apart from the body surface of the napkin body and extends along a longitudinal centerline of the napkin body. The side wall portions connect at the apex and diverge toward the body surface of the napkin body. The apex and the side wall portions are different in stiffness. The side wall portions have a space therebetween and are permitted to deform and approach each other.
