To provide a sanitary napkin excellent in the fitness to the body and hard to cause not only the inside falling of a leakproof wall but also the spreading leakage in its rear part.
Elastic stretchable parts 53 are fixed to the absorbent body 10 in the front and rear end parts of the leakproof walls 5 to form end fixing parts 54 and the inward sides in the width direction Y of the elastic stretchable parts 53 are fixed to the absorbent body 10 or erected parts 52 between both front and rear end parts to locally form intermediate fixing parts 55. The leakproof walls 5 are divided into front leakproof walls 5A and rear leakproof walls 5B on the basis of the intermediate fixing parts 55 and the front leakproof walls 5A are longer than the rear leakproof walls 5B in the longitudinal direction Y of the absorbent body 10. The inward sides in the width direction X of the elastic stretchable parts 53 of the rear leakproof walls 5B are fixed to the absorbent body 10 or the erected parts 52 over the whole length in the longitudinal direction of the absorbent body 10 and the fixing widths thereof are shorter than those of the elastic stretchable parts 53 in the intermediate fixing parts 55. The front leakproof walls 5A and the rear leakproof walls 5B are different in cross-sectional shape along the width direction X.
