The invention discloses a sanitary towel which comprises a surface layer, an absorption layer and a leakage-proof bottom layer. The leakage-proof bottom layer is arranged in the middle of the inner side of the surface layer, and the absorption layer made of Hismer fibers is arranged in the middle of the inner side of the leakage-proof bottom layer; side absorption pits are transversely arranged onthe surface of the inner side of the absorption layer, and end absorption pits are longitudinally arranged on the surface of the inner side of the absorption layer; side leakage-proof pits are transversely arranged on the surface of the inner side of the leakage-proof bottom layer, and end leakage-proof pits are longitudinally arranged on the surface of the inner side of the leakage-proof bottomlayer. The sanitary towel has the advantages that the sanitary towel is reasonable and simple in structural design, is clean and sanitary and has healthcare functions, good side-leakage-proof effectscan be realized by the sanitary towel, and popularization of the sanitary towel can be facilitated.
