Abstract
A sanitary napkin includes a napkin body containing a liquid absorbent layer and a three-dimensional structure is disposed on the skin-side surface of the napkin body. The three-dimensional structure is formed of an air-laid nonwoven fabric and a liquid-permeable sheet, and the air-laid nonwoven fabric is formed with upwardly extending compressed portions. The three-dimensional structure comes into close contact with the body's groove to effectively prevent lateral leakage of menstrual blood during sleep.
