PURPOSE: To solve such a problem that the excretion is easily left behind in a surface sheet since ridge portions of the corrugated surface sheet are separated from absorptive cores when a conventional sanitary napkin is curved. CONSTITUTION: The surface sheet 2 of the sanitary napkin is provided by alternately forming coarse portions 2c low in fiber density and dense portions 2d high in fiber density on ridge portions 2a of the corrugated nonwoven fabric. When the sanitary napkin is subjected to bodily pressure, the surface sheet 2 is curved and deformed at each coarse portion 2c. Since the ridge portions 2a are not folded by an unreasonable force at the dense portions 2d except the coarse portions 2c, the surface sheet 2 is prevented from being separated from the absorptive core 3. Degradation in permeability and diffusion between the surface sheet 2 and the absorptive core 3 can be prevented, and the excretion received by the surface sheet 2 can be effectively led to the absorptive core 3. |
