Patent ID: 7763001

Claim:
An absorbent article of an elongated shape having a longitudinal direction and a lateral direction, said article comprising: a fluid permeable top sheet; a fluid impermeable back sheet; an absorbent body, disposed between the top sheet and the back sheet, for absorbing and retaining body fluid; and a fluid permeable member comprising hydrophilically-processed synthetic resin fibers without water-absorbent resin and arranged along the longitudinal direction of the absorbent article, between the top sheet and the absorbent body; leakage prevention barriers arranged along and in vicinity of the longitudinal side edges of the absorbent article, respectively, wherein the fluid permeable member comprises: a fixed portion that is directly fixed to the absorbent body, a top face portion directly supporting the top sheet from below and along a longitudinal center line of the article, and an uprising portion that links the fixed portion and the top face portion and stands up in a thickness direction of the article upwardly from the absorbent body, the top face portion has a plurality of elastic members directly attached thereto so as to extend in the longitudinal direction parallel to the longitudinal center line of the absorbent article, and the top sheet has: a first attachment region that is directly attached to the top face portion along the longitudinal center line of the absorbent article, an unattached region that extends from longitudinal side edges of the top face portion toward respective longitudinal side edges of the absorbent article while being upwardly spaced from the absorbent body, and second attachment regions where the side edges of the top sheet extending in the longitudinal direction are positioned between the leakage prevention barriers and the absorbent body, respectively, in vicinity of the longitudinal side edges of the absorbent article, wherein the leakage prevention barriers have elasticized edges risable above, along and in vicinity of the longitudinal side edges of the absorbent article, respectively, and wherein the second attachment regions of the top sheet are formed below the elasticized edges of the leakage prevention barriers.
