Patent number: 5807363Abstract: An absorbent article has a substantially elongated shape and includes a topsheet 2, a backsheet 3, and an absorbent member 4. The topsheet 2 includes a sheet member which has one surface 2a exhibiting hydrophobic properties and another surface 2b exhibiting hydrophilic properties. The one surface of the topsheet is a skin contactable surface, and the other surface faces the absorbent member 4. The backsheet serves as an anti-leakage sheet and is disposed at opposing longitudinal side portions of an upper surface of the absorbent article inwardly from side edges 1a of the absorbent member so that the backsheet forms a pair of hydrophobic areas A. Each of the hydrophobic areas A has a continuous or discontinuous sealed portion 10 formed by sealing the topsheet 2 and the backsheet 3 along each inner edge A' of each hydrophobic areas A.
