The invention discloses a sanitary towel. The sanitary towel comprises a fabric layer, a chip layer, a flow guiding layer, a breathable bottom film, release paper and a coating which are sequentially stacked from top to bottom. A structural adhesive is arranged between the adjacent layers, a main core body is arranged between the flow guiding layer and the breathable bottom film, a breathable gathering and distributing part with the closed boundary is arranged in the center of the main core body, the length of the breathable gathering and distributing part is at least 10% larger than that of the main core body, the width of the breathable gathering and distributing part is at least 20% larger than that of the main core body, and the depth of the breathable gathering and distributing part is at least 30% larger than the thickness of the main core body. Side leakage is reduced through the breathable gathering and distributing part, vent holes are formed in the main core body, through the combination of the breathable gathering and distributing part and the vent holes, besides enough absorption capacity is kept, the breathability of the product is greatly improved, meanwhile, secretion absorption can be accelerated to reduce side leakage risks, therefore, physical and psychological health of a customer is benefited, and the use comfort is improved.
