The skin contact side sheet is protected and fastening of the absorbent body is secured while reliably suppressing liquid leakage. The sanitary napkin 1 is provided with an absorbent body 2 including a liquid permeable skin contact side sheet 3, a liquid impermeable non-skin contact side sheet, and an absorbent core 5 arranged between these skin contact side sheet 3 and non-skin contact side sheet. A cover sheet which covers the surface of the skin contact side sheet 3 is provided. At the cover sheet, partition lines are used to define a front wing 10F and back wing 10B for fastening the absorbent body 2 to the clothing. At the time of use, the front wing and back wing are folded and extended at the front folded region 14F and the back folded region 14B and fastened to the clothing. The partition lines are formed so that the front folded region 14F is positioned at the outside in the longitudinal direction from the front end edge 5F of the absorbent core 5 and so that the back folded region 14B is positioned at the inside in the longitudinal direction from the back end edge 5B of the absorbent core 5.
