Therefore, even if the side flap portion 6S is twisted while the napkin 1 is being worn, the twist of the side flap portion 6S is unlikely to propagate to the area where the fiber mass layer 42 is arranged. Therefore, according to the present embodiment, the effect of preventing the side flap portion 6S from being twisted by both the constricted portions 61 and 62 and the effect of preventing the absorbent body 4 from being twisted by the fiber mass layer 42 are combined to provide discomfort when wearing the napkin 1.
