Abstract
A sanitary napkin has leakage preventing walls on a skin-side surface of a main body. The leakage preventing wall has a skin-contacting portion, of which an inner edge is fixed at an inner edge's front end and an outer edge is fixed at an outer edge's front end located forward of the inner edge's front end. Therefore, when the leakage preventing wall is in a rising position, the skin-contacting portion is inclined with the outer edge closer to the wearer's body than the inner edge. Accordingly, the skin-contacting portion can easily conform to the wearer's crotch on both sides of the vaginal opening.
