A SANITARY NAPKIN INCLUDES A NAPKIN BODY (2) HAVING A LIQUID-ABSORBENT LAYER (22) FOR ABSORBING AND RETAINING LIQUID AND A PROJECTION (41) PROJECTING FROM A BODY SURFACE OF THE NAPKIN BODY. THE PROJECTION IS SECURED AT LATERALLY SPACED BASE ENDS TO THE BODY SURFACE OF THE NAPKIN BODY. A DISTANCE BETWEEN THE BASE ENDS VARIES LONGITUDINALLY OF THE PROJECTION. A HEIGHT OF THE PROJECTION FROM THE BODY SURFACE OF THE NAPKIN BODY DECREASES WITH INCREASING THE DISTANCE BETWEEN THE BASE ENDS.
