Abstract
A sanitary napkin includes a liquid-pervious topsheet, a liquid-absorbent core, a shape-retaining panel lining the core and a back side member. The core and the shape-retaining panel are configured so as to present inverted V-shaped cross-sections, respectively, and attached to the back side member which is substantially flat. The napkin thus constructed allows at least the inverted V-shaped cross-sections to follow a movement of the wearer's body.
