The purpose of the present invention is to obtain an absorbent article that has stable absorbability when worn and is more comfortable to use by preventing liquid leakage and stuffiness, the absorbent article enabling the natural absorbability of an absorption core to be fully exhibited and the leakage of liquid such as excreted liquid and stuffiness when worn to be stably suppressed. More specifically, an absorber (13) is configured to be provided with an absorption core (15) which extends in the length direction of the absorber (13) and absorbs and holds liquid, and a covering sheet (16) which has liquid permeability and is wrapped around the outer peripheral surface of the absorption core (15) about the axis in the length direction of the absorption core (15), the covering sheet (16) has extension parts (18) each of which extends from an end in the width direction of the absorption core (15) and the inner peripheral surface side of each of which is not in contact with a liquid permeable sheet (11)-side surface and a liquid impermeable sheet (12)-side surface of the absorption core (15), and an absorbent material (19) having liquid absorbability is bonded to the inner peripheral surface side of each of the extension parts (18) by a bonding agent.Lobjet de la présente invention est dobtenir un article absorbant qui présente une capacité dabsorption stable lorsquil est porté et qui est plus confortable à utiliser, en empêchant une fuite de liquide et un manque daération, larticle absorbant permettant le déploiement total de la capacité naturelle dabsorption dun noyau dabsorption et une suppression de manière stable de la fuite de liquide tel que des liquides excrétés et du manque daération lorsquil est porté. Plus particulièrement, un absorbant (13) est conçu pour être pourvu dun noyau dabsorption (15) qui sétend dans le sens de la longueur de labsorbant (13) et qui absorbe et retient le liquide, et dune feuille de recouvrement (16) qui est perméable aux liquides et
