A sanitary napkin comprising:
- a base member formed from a liquid-pervious topsheet, a liquid-impervious backsheet, and a liquid-absorbent core disposed between said liquid-pervious topsheet and said liquid-impervious backsheet, said base member having an upper surface, transversely opposite outer side portions extending in a longitudinal direction of said sanitary napkin and longitudinally opposite end portions extending in a transverse direction of said sanitary napkin;
- and
- a pair of barrier flaps formed on upper surfaces of said transversely opposite outer side portions so as to extend along said transversely opposite outer side portions between said longitudinally opposite end portions,
- each barrier flap of said pair of barrier flaps having a fixed edge portion which extends in said longitudinal direction and a free edge portion which extends in said longitudinal direction, and a pair of longitudinally opposite end portions,
- each barrier flap of said pair of barrier flaps being fixed to the upper surface of said base member only at the fixed edge portion and the longitudinally opposite end portions of the barrier flap, the opposite end portions of each barrier flap being fixed flatly against the upper surface of the base member across an entire width of each barrier flap,
- said free edge portion of each barrier flap of said pair of barrier flaps being stretchable outward transversely of said base member so as to extend outward beyond transversely opposite side edges of the base member when worn by a wearer.
The sanitary napkin according to clam 1, wherein said free edge portion of each barrier flap of said pair of barrier flaps is stretchable outward transversely of said base member so as to extend outward beyond tersely opposite side edges of the base member along a longitudinal length of said barrier flaps that extends between the longitudinal opposite ends of the barrier flaps which opposite ends are fixed to the upper surface of the base member.
