An absorbent article (10) has a crotch region (S1), a pair of wait regions (S2, S3) located both sides of the crotch region in the front-rear direction, an absorbent body (40) having an absorbent core (45), and an exterior body (15) disposed on the non-skin facing side of the absorbent body in at least one of the pair of waist regions. The exterior body has a pair of sheet materials (18) and an elastic member (50) disposed between the pair of sheet materials and extending in the width direction. The elastic member has a continuous elastic member (52) that is continuously elastic from one outer side part of the exterior body to the other outer side part of the exterior body in the width direction. The exterior body is provided with: a non-fixing region (R12) in which the continuous elastic member is not fixed to the pair of sheet materials at the center of the absorbent article in the width direction; and a pair of fixing regions (R11) in which the continuous elastic member is fixed in an expandable/contractible manner to at least one of the pair of sheet materials in the outer sides of the non-fixing region in the width direction. Each of the pair of fixing regions is disposed across the outer edge of the absorbent body in the width direction.L'invention concerne un article absorbant (10) qui comprend une région d'entrejambe (S1), une paire de régions de taille (S2, S3) situées sur les deux côtés de la région d'entrejambe dans la direction avant-arrière, un corps absorbant (40) ayant un noyau absorbant (45), et un corps extérieur (15) disposé sur le côté non tourné vers la peau du corps absorbant dans au moins une des régions de la paire de régions de taille. Le corps extérieur comprend une paire de matériaux en feuille (18) et un élément élastique (50) disposé entre la paire de matériaux en feuille et s'étendant dans le sens de la largeur. L'élément élastique comprend un élément élastique continu (52) qui est élastique de façon continue à partir d'une partie latéra
