PROBLEM TO BE SOLVED: To hardly generate a gap between a skin surface and an absorbent article in wearing, and prevent leakage of biological fluid.SOLUTION: A sanitary napkin 1 is such that a wing-like flap W is formed on each of both side parts of a body part where an absorber 4 is present between a liquid permeable top sheet 3 and a rear surface sheet 2, and is folded in the longer direction by a plurality of width direction folding lines X1-X3 in an individual packaging state. One width direction folding line X2 in the plurality of width direction folding lines is a formation range A1 of solid gathers BS, and is provided in a range 22 on which a leg pressure from both sides to the inner side when wearing acts. The width direction folding lines X1 and X3 excluding the line X2 are provided in a formation range of a rear adhesion area A3, or both of a formation range of the rear adhesion area A3 and a formation range of a front adhesion area A2.
