Abstract
There is disclosed an absorbent article including: a body portion including, a liquid permeable front surface sheet for facing the wearer, a back surface sheet, and an absorbent layer sandwiched between the front surface sheet and the back surface sheet; and leakage preventing walls extending in a longitudinal direction of the body portion and arranged at two sides thereof in a width direction perpendicular to the longitudinal direction. The leakage preventing wall includes a side wall part upstanding from the surface of the body portion and a skin contacting part extending from the upper end of the side wall part toward the outside of the body portion in the width direction. A fold inducing part is formed to extend in the longitudinal direction at a middle part between the upper end and the lower end of the side wall part, whereby the side wall part is folded with the fold inducing part moved toward the outside of the body portion in the width direction when the skin contacting part is pressed toward the surface of the body portion.
